Noctuidae
The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. Taxonomically, they are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae.
Adult: Most noctuid adults have wings with a variety of shades of browns, grays, and other varied shades and colourations but some subfamilies, such as Acronictinae and Agaristinae, are very colorful, especially those from tropical regions (e.g. Baorisa hieroglyphica). They are characterized by a structure in the metathorax called the nodular sclerite or epaulette, which separates the tympanum and the conjunctiva in the tympanal organ. It functions to keep parasites (Acari) out of the tympanal cavity. Another characteristic in this group is trifine hindwing venation, by reduction or absence of the second medial vein (M2).[page needed]
Markings present on the wings of noctuid adults can be helpful in distinguishing species. From the basal location to the outer edge (proximal to distal) on the forewing, there is a horizontally oriented claviform (club-shaped) stigma located posterior to a discal (round) stigma. These are followed distally by a reniform (kidney-shaped) stigma, whose exact shape may vary, but is found on the distal edge of the forewing's cell. It is often not possible to discern all of the stigmata on all specimens or species. Crossbands or crosslines may be present, oriented longitudinally from the leading to the trailing edge of the wing.
Larva: Commonly green or brown; some species present bright colors, such as the camphorweed cucullia moth (Cucullia alfarata). Most are pudgy and smooth with rounded short heads and few setae, but there are some exceptions in some subfamilies (e.g. Acronictinae and Pantheinae).
Pupa: The pupae most often range from shiny brown to dark brown. When they newly pupate they are bright brownish orange, but after a few days start to get darker.[citation needed]
Eggs: Vary in colors, but all have a spherical shape.[citation needed]
The word Noctuidae is derived from the name of the type genus Noctua, which is the Latin name for the little owl, and the patronymic suffix -idae used typically to form taxonomic family names in animals.
The common name "owlet" originally means a small or young owl. The names "armyworms" and "cutworms" are based on the behavior of the larvae of this group, which can occur in destructive swarms and cut the stems of plants.
