Myrmecocystus honeypot ants, showing the repletes or plerergates, their abdomens swollen to store honey, above ordinary workers

Honeypot ants, also called honey ants, are ants which have specialized workers—repletes, plerergates or rotunds—that consume large amounts of food to the point that their abdomens swell enormously. This phenomenon of extreme inflation of the trunk is called physogastry.[1] Other ants then extract nourishment from them, through the process of trophallaxis. They function as living larders. Honeypot ants belong to any of several genera, including Myrmecocystus and Camponotus. They were first documented in 1881 by Henry C. McCook, and described further in 1908 by William Morton Wheeler.

Behaviour

[edit]

Many insects, notably honey bees and some wasps, collect and store liquid for use at a later date. However, these insects store their food within their nest or in combs. Honey ants are unique in using their own bodies as living storage, used later by their fellow ants when food is otherwise scarce. Designated worker ants, called "repletes," are the main group that store food for the colony. Repletes are fed by other worker ants until their abdomens become swollen with honey.[2] This extreme growth causes the repletes to become mostly immobile as they act as the "living pantry" for the colony.[3][4] When the liquid stored inside a honeypot ant is needed, the worker ants stroke the antennae of the honeypot ant, causing the honeypot ant to regurgitate the stored liquid from its crop.

Anatomy

[edit]
Honeypot ants compared to a human hand. The dark dorsal sclerites are widely separated by the stretched arthrodial membrane of the inflated abdomen of each replete.

The abdomen of species like Camponotus inflatus consists of hard dorsal sclerites (stiff plates) connected by a softer, more flexible arthrodial membrane. When the abdomen is empty, the arthrodial membrane is folded and the sclerites overlap, but when the abdomen fills the arthrodial membrane becomes fully stretched, leaving the sclerites widely separated.[5]

Honey

[edit]

The honey from honeypot ants is unique. Like bee honey, it has antimicrobial effects against pathogens and decay organisms, but it differs from bee honey, for example in having a higher moisture content. Honeypot honey has a significantly lower concentration of sugar than bee honey from manuka and jarrah for example. The ant honey is not concentrated only from nectar and other sweet components of the diet, but also from metabolites of plant and animal food sources in general. The honey has a slightly acidic pH, and contains phenolic compounds.[6] It also contains a disaccharide of unknown function, that still was unidentified in 2023.[6][7]

Ecology

[edit]

Myrmecocystus nests are found in a variety of arid or semiarid environments. Some species live in extremely hot deserts, others reside in transitional habitats, and still other species can be found in woodlands which are somewhat cool but still very dry for a large part of the year. Honey pot ants have been reported to be in the USA (specifically Colorado and New Mexico), Mexico, the African continent, and Australia.[8][9][7] For instance, the well-studied Myrmecocystus mexicanus resides in the arid and semiarid habitats of the southwestern United States. Sterile workers in this species act as plerergates or repletes during times of food scarcity. When the plerergates are fully engorged, they become immobile and hang from the ceilings of the underground nests. Other workers drain them of their liquid food stores to feed the rest of the colony. Plerergates can live anywhere in the nest, but in the wild, they are found deep underground, unable to move, swollen to the size of grapes.

In Camponotus inflatus in Australia, repletes formed 49% (516 ants) of a colony of 1063 ants, and 46% (1835 ants) of a colony of 4019 ants. The smaller colony contained six wingless queens. The larger colony had 66 chambers containing repletes, with a maximum of 191 repletes in a chamber. The largest replete was 15 millimetres long and had a mass of 1.4 grams. The nest had a maximum depth of 1.7 metres, and tunnels stretched 2.4 metres from the nest entrance. The workers went out foraging during daylight to collect nectar from Mulga nectaries, and meat from the carcass of a Tiliqua blue-tongued lizard.[10]

Recent findings

[edit]

Bee honey is an effective natural remedy for a wide range of ailments. But very little research has been done on other types of honey, produced by different insects, up until recently.[when?] The antimicrobial activity of honey from honey pot ants was tested and compared to the antimicrobial activity of bee honey. It was found that honeypot ant honey has activity against bacteria, yeast, and mold. When honey pot ant honey was compared against jarrah or manuka bee honeys, a distinctly different activity profile was found. Honey pot ant honey outperformed the other two honeys against some pathogens, but exhibited low/no activity against other ones.[6]

Genera

[edit]

Honeypot food storage has been adopted in several seasonally active ant genera:[11]

Cultural significance

[edit]
Digging for honey ants
Further information: Entomophagy, Insects as food, and Insects in culture

Honeypot ants such as Melophorus bagoti and Camponotus are edible insects and form an occasional part of the diet of various Indigenous Australians. These people scrape the surface to locate the ants' vertical tunnels, and then dig as much as two metres deep to find the honeypots. Papunya, in Australia's Northern Territory, is named after a honey ant creation story, or Dreaming, which belongs to the people there, such as the Warlpiri. The honey ants were celebrated in the Western Desert Art Movement's The Honey Ant Mural, painted in 1971. In Central Australia, there is a Honey Ant Dreaming site that is shared by all indigenous groups around the area.[14] For these indigenous groups, the honey pot ant represents their Dreaming or Tjukurpa, the philosophy based on the spiritual connection between people and things.[15][4]

Honeypot ants are an important part of the culture for Australian Aboriginal people. A Tjupan legend says that mothers who sit and gather honey ants for long periods of time, will start to neglect their children, leaving her and her children vulnerable to enemies who want to slay. This story has been passed down from many generations to remind women to be aware of their surroundings when sitting and gathering.[7]

For numerous indigenous groups, collecting honey ants is viewed as a women's job. Digging for ants is viewed as a social gathering for women to converse and interact. Children are often included so they learn the cultural and location-specific knowledge in locating the underground ant colonies.[7]

Indigenous medicinal use

[edit]

Indigenous Australians from the Tjupan language group use honeypot ant honey to treat sore throats, colds, and as a topical ointment to treat skin infections. A Sydney University study has investigated the efficacy of honey from Camponotus inflatus, and found it effective against the bacterium Staphylococcus aureus, and the fungi Aspergillus and Cryptococcus. The antimicrobial mechanism is significantly different to that of Mānuka honey.

from Grokipedia
Honeypot ants are of distinguished by a unique of specialized workers called repletes, whose abdomens expand dramatically to store liquid carbohydrates, proteins, and other nutrients, serving as living larders that sustain the colony during food shortages in arid environments. These primarily belong to the genera Myrmecocystus in the , , and parts of , and Camponotus in and other regions, with their evolution tied to the of these landscapes. In Myrmecocystus species, such as M. mimicus and M. mexicanus, colonies construct deep underground nests, often extending up to 1.7 meters, with dedicated chambers where immobile repletes hang from the ceiling, fed via trophallaxis by foraging workers that collect , honeydew, and . Repletes can swell to the size of small grapes, weighing up to 1.4 grams, and their abdomens feature flexible membranes between rigid sclerites that accommodate the stored liquid without bursting. This storage mechanism ensures colony survival during prolonged droughts, as nestmates solicit food from the repletes by antennal stroking, a that can support up to 49% of the colony population in some nests. Similarly, in Australian honeypot ants like Camponotus inflatus, workers harvest nectar from plants such as the mulga tree () in semi-arid , overfeeding select workers to produce a golden-brown stored in their abdomens, which exhibits high activity and low for preservation. These ants demonstrate across genera, with repletes playing a critical ecological role in nutrient distribution and colony resilience in harsh, resource-limited habitats. Beyond their biological significance, honeypot ants hold cultural value; in both and have long harvested and consumed the sweet liquid from repletes as a traditional .

Taxonomy and Classification

Genera and Species

Honeypot ants belong to the subfamily Formicinae within the family Formicidae, where the specialized storage of liquid food in repletes has arisen through across multiple unrelated genera. This adaptation allows certain worker ants to function as living reservoirs during periods of scarcity in arid environments. The primary genus associated with honeypot ants is Myrmecocystus, endemic to , encompassing approximately 31 described species primarily distributed in arid and semi-arid regions of the , , and southwestern . Notable species include Myrmecocystus mimicus, a diurnal forager commonly found in the deserts of the , and Myrmecocystus mexicanus, known for its widespread occurrence across similar habitats. In a recent taxonomic update, a new species of Myrmecocystus was described from the Pacific coastal dunes of , , highlighting ongoing discoveries in this genus. Beyond Myrmecocystus, honeypot ants appear in several other genera within Formicinae, reflecting the repeated of repletism. These include Camponotus (e.g., Camponotus inflatus in ), Melophorus (), Cataglyphis (), Leptomyrmex (), and Plagiolepis (). Each genus exhibits this trait independently, underscoring its adaptive value in resource-limited ecosystems.

Evolutionary Origins

The honeypot ant trait, characterized by repletes that store liquid food in distended abdomens, was first documented in 1881 by Henry C. McCook in his study of the Myrmecocystus from the in . McCook's observations detailed the unique morphology and role of these "honey ants," marking a key early contribution to understanding their biology in North American arid regions. Repletism has arisen through in at least six ant worldwide, including Myrmecocystus and Camponotus, as an adaptive strategy in response to arid environmental pressures. This polyphyletic origin reflects independent evolution of the honeypot trait across distantly related lineages, driven by the need for food storage in unpredictable desert ecosystems. Phylogenetic analyses indicate that the trait likely emerged multiple times, with the oldest known fossil replete worker dating to the epoch approximately 20 million years ago in the genus Leptomyrmex, and ancestral state reconstructions estimating its origin in the Eocene around 45 million years ago. For Myrmecocystus specifically, genetic studies using ultraconserved elements place the genus within the genus group, as the sister to Lasius, with their divergence occurring in the early around 18.5 million years ago. Crown-group diversification of Myrmecocystus began approximately 14 million years ago, coinciding with the of the American Southwest, which favored the of specialized repletes from ancestral generalist foragers to enhance survival during food scarcity. This underscores repletes as an autapomorphy for the , promoting rapid in harsh, variable habitats.

Distribution and Habitat

Geographic Range

Honeypot ants are primarily distributed across arid and semiarid regions worldwide, with no native populations in humid or temperate zones. Their range is confined to dry ecosystems where drives the of repletes for storage. In , the genus Myrmecocystus dominates, occurring in arid ecosystems from southwestern , , through the —including deserts in and —and extending into the majority of . For example, Myrmecocystus mimicus is found in the southwestern U.S. and northern , often in large colonies numbering in the thousands within soils. Myrmecocystus mexicanus thrives specifically in the , such as the regions of and . Australia hosts several honeypot ant species in its outback and arid interiors. Camponotus inflatus is common in mulga woodlands of the and , where colonies excavate extensive nests in red desert soils. The genus Melophorus, including Melophorus bagoti, inhabits central 's semi-desert habitats, contributing to high local densities in hot, sandy environments. In , species of exhibit honeypot traits in desert regions, ranging from the across , , and to parts of the . These ants maintain colonies in hyper-arid sands, with limited expansion due to extreme temperatures. Honeypot ants in the genus Leptomyrmex are restricted to , particularly and surrounding islands, where they occupy dry forest edges and savannas. In , Plagiolepis trimeni occurs in arid zones of , forming nests in sandy soils of the region. Overall, honeypot ants show no significant range expansions or contractions as of pre-2025 observations, remaining tightly linked to dry habitats; however, may affect desert edge populations through altered patterns. densities vary, with examples like Myrmecocystus nests in U.S. s supporting thousands of individuals across interconnected chambers.

Arid Environment Adaptations

Honeypot ants exhibit remarkable nest architectures tailored to the challenges of arid environments, where surface conditions are often hot and desiccating. Colonies construct extensive underground systems in sandy or loamy soils, with tunnels and chambers extending to depths of 1 to 5 meters to reach more humid subsurface layers and stabilize internal microclimates. In North American species of the Myrmecocystus, such as M. mimicus, nests consist of a of horizontal passages branching up to 2.4 meters from the entrance and vertical shafts descending 1.7 meters, culminating in specialized domed replete chambers positioned 20–35 cm below the surface for humidity retention. Similarly, Australian honeypot ants in the Melophorus, including M. bagoti, feature deep subterranean replete chambers that protect stored liquids from and fluctuations, enhancing colony longevity in semi-arid habitats. Water conservation is achieved through a combination of physiological and behavioral mechanisms that minimize loss in non-replete workers while relying on repletes for overall colony hydration. Non-replete foragers and nest workers in Myrmecocystus species demonstrate high tolerance, with cuticular permeability adapted to low loss rates even at elevated temperatures up to 40°C, allowing brief surface excursions without fatal . Colonies also enter periods of reduced activity during extreme dry seasons, effectively entering a state of behavioral quiescence to limit metabolic expenditure, particularly in the hot summer months when resources are scarce. This tolerance extends to repletes, whose distended abdomens store not only carbohydrates but also -rich , serving as a to distribute moisture via trophallaxis to vulnerable larvae and workers. Foraging strategies are synchronized with environmental conditions to evade daytime heat and desiccation risks. Many Myrmecocystus species, such as M. mexicanus, exhibit nocturnal or crepuscular activity, with workers emerging primarily at night when temperatures range from 0.6°C to 27°C, reducing evaporative loss during excursions for from ephemeral sources like extrafloral nectaries. In contrast, certain Australian Melophorus honeypot ants, adapted to even more extreme , forage diurnally during the hottest periods, leveraging thermophilic to exploit brief windows of available from before resources vanish. This timing ensures efficient collection of transient, water-containing foods while minimizing exposure to lethal surface conditions. The colony's resilience to prolonged resource hinges on repletes functioning as living larders, buffering against in unpredictable arid ecosystems. In Myrmecocystus colonies, up to 1,030 repletes per nest can store sufficient liquid—primarily with high —for the entire colony to survive during periods of food , such as seasonal dry periods or winters. This allows non-repletes to remain inactive underground, conserving and water, while repletes hang immobile in chambers, their stored reserves sustaining the group through droughts that could otherwise decimate populations. Australian Melophorus employ analogous strategies, with deep replete storage enabling colony persistence during extended periods of aridity.

Morphology and Anatomy

General Body Structure

Honeypot , such as those belonging to the genus Myrmecocystus, display polymorphic worker castes with body lengths typically ranging from 3 to 7 mm, allowing for division of labor in foraging and nest maintenance. Coloration varies across species and genera but often includes shades of yellow to reddish-brown in Myrmecocystus; for instance, workers of Myrmecocystus mexicanus exhibit a light yellow body with a brownish tinge in southern populations, complemented by black mandibles and a darker head. In Australian species like Camponotus inflatus, workers are typically black with paler feet and sparse hairs. These lack wings in their worker stage, consistent with their ground-dwelling lifestyle. The head features prominently large compound eyes, which facilitate visual orientation and navigation during diurnal or nocturnal in open landscapes. Mandibles are robust and bear a varying number of teeth, typically 7 to 9 depending on the , enabling workers to grasp small prey, such as , and handle sources effectively. The , often shiny and pubescent in like Myrmecocystus mimicus, supports these activities and measures approximately 1.7 mm in length for typical foragers. Legs are equipped with tiny hairs that enhance traction on sandy substrates, supporting rapid excursions, while workers can adopt stilt-like postures for territorial displays and mobility. The gaster in non-replete workers remains compact and non-swollen, with standard segmentation and abundant pubescence aiding sensory detection, in contrast to the distended form seen in specialized storage castes.

Replete Specialization

Replete workers in honeypot ant colonies exhibit specialized anatomical adaptations that enable them to function as living food storage units, distinct from typical whose bodies feature a rigid composed of sclerites and intersegmental . The key modification occurs in the gaster, the posterior abdominal region, where a highly stretchable arthrodial connects the hard sclerites, allowing for dramatic expansion without structural failure. This elasticity arises from the unfolding of the unstretchable epicuticle and the presence of in the endocuticle, enabling the gaster to swell substantially—often to the size of a small —while displacing internal organs. As a result, fully engorged repletes lose mobility and typically hang passively from the ceilings of specialized nest chambers located 20–35 cm underground. Internally, the primary storage organ is the , a of the located posterior to the and anterior to the proventriculus, often referred to as the social stomach. This expandable structure holds large volumes of liquid food, such as or honeydew, without initiating , thanks to valvular mechanisms that isolate it from the . The crop's contents can vary in color from clear (potentially ) to dark (rich in glucose and ), and the organ's distension causes the abdominal sclerites to appear as small islands amid the stretched membrane. When full, repletes become immobile, relying on other workers for support within domed chambers designed to accommodate their swollen form. The development of repletes occurs through a trophogenic process, where certain worker larvae or newly emerged adults are selectively overfed by nestmates to promote abdominal enlargement, typically within two weeks of eclosion. This differentiation is influenced by resource availability and is not strictly age-limited, allowing flexibility in response to environmental conditions. In many species, such as Myrmecocystus mexicanus, the specialization is reversible; drained repletes become flaccid and can resume duties, with their abdominal sclerites twisting back into place. Physiologically, individual repletes can store liquid volumes equivalent to or exceeding their body weight, supporting during scarcity, while antimicrobial mechanisms—including acidic secretions (pH around 3.4) and potential non-peroxide compounds like peptides—prevent microbial spoilage of the stored food.

Behavior and Social Structure

Foraging and Collection

Honeypot ant colonies rely on non-replete workers to forage for essential resources in arid environments. These workers primarily collect liquid foods such as honeydew excreted by and scale insects, nectar from desert flowers including species of and , and occasionally solid items like and other scavenging . This diet supports the colony's survival by providing carbohydrates and proteins adapted to sparse availability. Foraging typically occurs in small groups or by solitary scouts, with patterns varying by food source profitability. Scouts initiate trails marked by pheromones from secretions, combined with motor displays and gland emissions to recruit additional foragers for rich patches. Workers collect liquids directly into their mouthparts and store them in the —a specialized social stomach—for without spillage, enabling efficient return to the nest. Adaptations enhance efficiency in harsh conditions, including the ability to traverse up to 50 meters from the nest at rates of 0.3 to 0.9 meters per minute. These diurnally or nocturnally depending on and temperature, tolerating surface heat up to 60°C while carrying loads in the to minimize loss. Group recruitment via pheromonal trails optimizes collection from ephemeral sources like blooming flowers. Seasonal variations dictate foraging intensity, with peaks in the post-rainy period (July–August) when nectar availability surges after blooms. During extreme droughts, activity diminishes significantly, conserving resources until conditions improve.

Repletism and Colony Dynamics

In honeypot colonies, repletes represent a specialized of workers that function as living units, enabling the colony to endure periods of resource scarcity. The colony structure includes responsible for egg-laying, foragers that collect and other liquids primarily from sources like plant exudates or honeydew, and the replete workers that store these resources internally. Colonies can vary in size, with examples in Camponotus inflatus reaching up to 4,019 individuals, including as many as 1,835 repletes comprising about 46% of the population. In species like Myrmecocystus mexicanus, colonies typically number around 5,000 , with repletes making up 22-25% of the workforce. Trophallaxis, the mouth-to-mouth exchange of liquid , is central to repletes' role in colony dynamics. Foragers regurgitate collected directly into the crops of developing repletes, causing their abdomens to distend significantly as storage capacity increases. Once engorged, repletes dispense this stored liquid to larvae, other workers, or the queen during times of food shortage, ensuring distribution throughout the colony without external storage. Repletes are maintained in dedicated underground chambers, where they are groomed, protected from disturbances, and periodically replenished by to sustain their engorged state, which can extend their lifespan compared to active workers. This role immobilizes them, suspending from chamber ceilings, but allows the to survive extended dry periods when is impossible. In mature , the accumulation of sufficient repletes supports the production of new and males for nuptial flights, perpetuating the colony lifecycle.

Food Storage and Honey

Mechanism of Storage

In honeypot ants of the Myrmecocystus, the storage of liquid food occurs in the , a of the that functions as an expandable . workers transfer or honeydew to prospective repletes through trophallaxis, a mouth-to-mouth exchange process. The proventriculus, a valvular structure at the junction between the and , closes to prevent the liquid from entering the digestive tract, allowing it to accumulate without enzymatic breakdown or absorption. This mechanism enables the to distend dramatically, swelling the gaster up to grape-sized proportions and displacing internal organs, while specialized cuticular elasticity in the abdomen accommodates the expansion without rupture. Preservation of the stored liquid relies on multiple biochemical barriers to inhibit microbial growth and . The crop contents are acidic, creating an environment hostile to many pathogens and spoilers. In Australian species such as Camponotus inflatus, the pH is around 3.4-3.85, and low levels of produced by enzymes like contribute to activity. In the swollen gaster, the tightly stretched and liquid-filled limit oxygen ingress, further reducing oxidative processes that could lead to spoilage. These combined factors ensure the nectar remains viable for extended periods, often months, in the arid environments where these ants thrive. Retrieval of the stored is achieved through controlled regurgitation, where a replete opens its to transfer directly to requesting workers or other members via trophallaxis. This on-demand dispensing supports during , though the immobile nature of repletes imposes an energy burden on the , as workers must continually groom and feed them to sustain the storage function. An individual replete can store volumes equivalent to several times its original body weight, providing carbohydrates sufficient for the 's needs over days or weeks, depending on size and environmental stress. As reserves deplete through repeated regurgitation, the contracts, causing the gaster to shrivel and the to become a non-functional "deplete," eventually dying if not replenished.

Honey Composition and Properties

The honey stored by honeypot ants, often referred to as honeypot ant honey, exhibits a distinct adapted for long-term storage within the ants' repletes, differing notably from that of bee-produced . In Australian species like Camponotus inflatus, it contains higher levels (33-36.5%) compared to the 17-20% in most bee honeys, contributing to its lower and more fluid consistency. The primary sugars are glucose and , comprising approximately 42-49% each of the total solids, with a fructose-to-glucose ratio around 0.85-1.0; sugar concentrations are generally lower, at 63-67° , than the 79-83° Brix typical of bee honeys. An unidentified minor , distinct from , is also present, alongside trace amounts of proteins (up to 9.45% in some species) and organic acids that impart a slightly sour . Unlike , which often includes and relies on or for antimicrobial effects, honeypot ant honey lacks these compounds but demonstrates unique non-peroxide antimicrobial activity. Its pH, typically around 3.4-3.85 in C. inflatus, supports this activity, inhibiting growth of bacteria such as (minimum inhibitory concentration of 8-100%) and fungi including and species, as well as certain yeasts and molds. , at levels of 19.6-159 mg equivalents per 100 g, further contribute to its properties, with DPPH radical scavenging activity up to 1367 µmol /kg. Composition varies by species and source material, reflecting regional adaptations. In North American species like Myrmecocystus mexicanus and M. mimicus, the liquid is primarily derived from floral , resulting in a mix dominated by and with 7-8% ; clear variants may contain higher levels for water storage functions. Australian species such as Camponotus inflatus source it mainly from honeydew excreted by hemipterans on trees, leading to slightly higher phenolic content and a more pronounced acidic profile, modified enzymatically in the ants' crop during regurgitation and storage. These variations influence and stability, with the honey remaining less viscous overall due to elevated moisture and reduced sugar density. Nutritionally, honeypot ant honey provides high energy from its content but is perishable upon extraction due to the higher levels, which accelerate microbial spoilage outside the sterile replete environment. Its trace proteins and acids enhance , though exact yields are low, requiring numerous repletes for significant quantities.

Ecology and Interactions

Habitat Role and Survival Strategies

Honeypot ants, particularly species in the Myrmecocystus, contribute to arid ecosystems through and , with occasional incidental seed transport. Their subterranean nests, featuring extensive networks, aerate compacted soils by excavating and redistributing earth, which improves penetration and nutrient availability during infrequent rains. Foraging trips to flowers for carbohydrate-rich nectar also enable services, supporting the reproduction of drought-adapted flora in regions like the . While workers occasionally collect seeds alongside nectar and insects, this is not a primary and does not constitute a major role in . Survival strategies center on repletes—specialized workers whose abdomens expand to store and honeydew, functioning as mobile larders that sustain the during famines when is impossible. Nests extend to depths of up to 3 meters, creating insulated chambers that regulate internal temperatures and protect against diurnal extremes exceeding 40°C on the surface. is opportunistic, with queens founding new colonies via mating flights triggered by post-rain humidity spikes, ensuring synchronized establishment in seasonally viable conditions. Colonies typically endure 10–15 years, bolstered by queens with lifespans exceeding 11 years that oversee worker production and replete maintenance. Population dynamics feature high replete turnover during harsh periods, where these individuals can comprise 46–49% of colony members to buffer resource shortages, though depletion occurs as they regurgitate stores to nestmates. These mechanisms enhance against droughts, with repletes and deep nests enabling colonies to persist through months of by conserving water and energy in microhabitats. However, extended arid conditions beyond typical cycles heighten , as reduced rainfall curtails and breeding, potentially leading to colony decline in increasingly dry landscapes. As of 2025, habitat loss from and , exacerbated by , poses additional threats to honeypot ant populations.

Symbiotic and Predatory Relationships

Honeypot ants, particularly species in the Myrmecocystus, form mutualistic relationships with and other homopterans by tending these to harvest their honeydew secretions, a key carbohydrate source that workers collect and transport back to the . This interaction benefits the aphids through protection from predators and parasitoids, while providing the ants with a reliable, renewable food supply during periods. Additionally, by visiting flowers to collect , honeypot ants inadvertently facilitate of arid-adapted plants, contributing to the of species in resource-scarce environments. Similar mutualisms occur in Australian Camponotus honeypot ants, which also tend hemipterans for honeydew. Occasional associations occur with myrmecophilous beetles, such as Cremastocheilus stathamae, which are observed entering nests of M. mimicus; these beetles may feed on secretions or waste within the nest, though the exact nature of the relationship remains incompletely understood. Predatory pressures on honeypot ants primarily target foraging workers rather than immobile repletes, which remain safely underground and are rarely consumed due to their stationary position within nest chambers. , such as the round-tailed horned lizard (Phrynosoma modestum), actively prey on Myrmecocystus foragers by ambushing them at colony entrances or trails, exploiting their clumped distribution for efficient hunting. Birds, including insectivorous species like roadrunners and , and spiders also consume exposed workers during foraging excursions, adding to the risks faced by surface-active ants in open desert habitats. Interspecific competition for nectar and honeydew resources is intense among honeypot ants and co-occurring ant species, leading to spatiotemporal partitioning of foraging areas to minimize overlap. Myrmecocystus mimicus workers establish temporary territories around productive nectar sources, using ritualized displays and to deter rivals like Conomyrma bicolor, which employs stone-dropping interference tactics against honeypot foragers. Larger "soldier" workers, characterized by robust mandibles and enhanced size dimorphism, play a crucial role in aggressive defense, engaging in physical confrontations or raiding smaller colonies to secure food supplies or even steal repletes. Reports of parasitic interactions in honeypot ants are limited, with few documented cases of compared to other ant genera. However, potential vulnerabilities exist in humid nest regions, where fungal infections could theoretically proliferate if moisture levels rise, though specific instances in Myrmecocystus species remain rare and understudied.

Human and Cultural Aspects

Historical and Indigenous Uses

Honeypot ants, particularly species like Camponotus inflatus, hold profound cultural significance among Australian Aboriginal peoples, featuring prominently in Dreamtime stories known as Honey Ant Dreaming. These narratives, shared across Indigenous groups in , portray the ants as embodiments of Tjukurpa, the spiritual philosophy linking people, land, and ancestral beings. The community, for instance, derives its name from a creation story centered on honeypot ants, underscoring their role in ancestral lore and communal identity. Indigenous Australians have long harvested honeypot ants as a vital source, especially during lean seasons in arid environments where they provide a rare natural . Women traditionally lead the gathering, excavating vertical shafts up to two meters deep near mulga trees to access underground nests, then tunneling sideways to reach the repletes while taking only a small portion to sustain the colony. The ants are consumed fresh or crushed for their sweet content, serving as a in ceremonies and daily sustenance that fosters family bonds through shared labor. Representations of honeypot ants appear in traditional , such as drawings and contemporary paintings, symbolizing the desert's "living larders" that embody resilience and abundance in harsh landscapes. In , honeypot ants of the genus Myrmecocystus, including M. mexicanus and M. navajo, were considered delicacies by Native Americans in the and , serving as a source during times of scarcity. Historical accounts suggest that North American also used honeypot ant medicinally, though documentation is limited.

Modern Culinary and Medicinal Applications

In contemporary cuisine, honeypot ants are consumed either whole as a sweet or with their stored honeydew extracted for use in dishes. In , these ants have achieved premium status, appearing in desserts at high-end restaurants focused on native ingredients, often incorporated into innovative recipes that revive Indigenous culinary traditions. For example, the ants' swollen abdomens are bitten to release the liquid, providing a honey-like flavor with a slightly sour undertone. In , such as Myrmecocystus melliger and M. mexicanus are savored as treats, typically held by the head and gently squeezed to consume the contents. Medicinally, honeypot ant honey continues to be applied in remedies for sore throats and coughs, drawing from longstanding practices now integrated into modern herbal approaches. There is growing interest in its use for due to the liquid's purported soothing and protective qualities when applied topically. Extraction methods involve manually locating underground colonies in arid regions and carefully removing the replete workers, followed by squeezing the honey from their distended abdomens, often after to facilitate collection. Harvesting in involves ethical practices guided by Indigenous knowledge, with challenges in wild collection due to the ants' remote habitats and the need to comply with wildlife regulations for non-listed . Commercially, honeypot ant honey is marketed as a niche product in outlets, valued for its unique nutritional profile that includes approximately 67 grams of sugars per 100 grams—primarily glucose for rapid release—alongside moderate phenolic content supporting its appeal in supplements. Prices reflect , with individual ants fetching around $20, positioning them as luxury items in edible insect markets.

Recent Research

Antimicrobial Discoveries

Research on the antimicrobial properties of honeypot ant honey has primarily focused on the Australian species Camponotus inflatus, revealing significant antibacterial and antifungal activity. A 2023 study published in PeerJ examined honey collected from repletes of C. inflatus and demonstrated its effectiveness against the bacterium Staphylococcus aureus and the fungus Candida albicans, as well as several molds, through inhibition zones in antimicrobial assays. The honey also exhibited low microbial load in its stored form, contributing to its long-term stability and reduced risk of contamination. This efficacy was found to surpass that of Manuka honey against certain pathogens, including S. aureus and C. albicans, highlighting the honeypot ant honey's potential as a superior natural agent in comparative tests. The mechanisms underlying this activity involve the production of and compounds similar to , which were identified as key contributors to the observed inhibition. Testing was conducted using standard disk diffusion assays, where honey samples were applied to plates inoculated with target microbes to measure zones of inhibition. Additionally, unique peptides were detected in the honey, potentially enhancing its broad-spectrum effects beyond those seen in typical plant-derived honeys. These findings underscore the implications of honeypot ant honey as a source of natural antibiotics, particularly in addressing antibiotic-resistant infections, and validate its traditional medicinal use by Indigenous Australian communities. However, research prior to 2025 has been limited to Australian species like C. inflatus, with gaps remaining in testing non-Australian honeypot ants, such as those in the North American genus Myrmecocystus, for comparable properties.

Genomic and Behavioral Advances

Recent genomic studies on Myrmecocystus species, key representatives of honeypot ants, have advanced understanding of repletism—the physiological adaptation enabling certain workers to serve as living units. A 2024 phylogenomic analysis of myrmicine tribes, including Myrmecocystus, utilized genome-scale data to resolve evolutionary relationships within the subfamily. Similarly, the newly described Myrmecocystus baja from dunes, reported in 2024, shows genetic differentiation driven by coastal habitats. A 2024 study further demonstrated this differentiation in M. baja populations, highlighting adaptations to arid coastal environments that may relate to repletism. These findings underscore how environmental pressures in arid ecosystems select for traits enhancing colony resilience during resource scarcity. Behavioral investigations post-2023 have employed innovative tracking methods to dissect dynamics in honeypot s. A planned 2026 project at the will use automated fluorescent flow tracking in Myrmecocystus colonies to quantify movement patterns, showing potential for efficient collection routes while minimizing energy expenditure on replete maintenance. In the Australian Melophorus bagoti, a 2023 study detailed "dumping" waste patterns, where specialized workers learn optimal disposal sites through experience, reducing nest contamination and supporting —insights potentially applicable to Myrmecocystus . A 2025 ecological paper further revealed that diel rhythms in communities remain stable despite experimental exposure to artificial at night, indicating robust behavioral plasticity against anthropogenic disturbances. A 2025 review emphasized repletism's pivotal role in sustaining within arid communities, where honeypot s facilitate resource buffering that stabilizes multi-species interactions during droughts. It also addressed methodological challenges, such as cross-contamination risks in metagenomic sequencing of replete microbiomes, advocating for refined protocols to isolate host-specific genetic signals. Looking ahead, ongoing projects previewed for 2026, including a initiative on colony genomics, aim to explore the reversible physiological states of repletes—such as transitions between storage and foraging roles—and their genomic underpinnings, potentially informing broader eusocial adaptations.
