Epargyreus clarus
Epargyreus clarus, the silver-spotted skipper, is a butterfly of the family Hesperiidae. It is claimed to be the most recognized skipper in North America. E. clarus occurs in fields, gardens, and at forest edges and ranges from southern Canada throughout most of the United States to northern Mexico, but is absent in the Great Basin and western Texas.
E. clarus larvae create and reside in unique shelters stuck together with silk, which do not protect them from predators. Natural predators of the species include paper wasp foragers, sphecid wasp and Crematogaster opuntiae ants. The species is also considered to be a perching species, meaning that adult males compete for territory to attract females. Although E. clarus is considered to be a pest of a few crop plants such as beans, its pest activity is not serious enough to warrant initiating major control measures.
Epargyreus clarus has a wide distribution throughout North America: it ranges from southern Canada throughout most of the United States to northern Mexico, but is absent from the Great Basin and western Texas.
The silver-spotted skipper prefers open ranges where nectar plants are found, such as forest edges, swamps, brushy areas, and riparian habitats at lower elevations.
At night, or on hot or cloudy days, Epargyreus clarus rests on the underside of a leaf. It hangs upside down, holding its wings together over its back so that its silver spot is exposed. E. clarus is often restricted by its habitat, preferring to fly in the shade.
Epargyreus clarus caterpillars consume leaves of herbs, vines, shrubs, and trees in the pea family (Fabaceae) including false indigobush (Amorpha fruticosa), American hogpeanut (Amphicarpaea bracteata), groundnut (Apios americana), American wisteria (Wisteria frutescens), Atlantic pigeonwings or butterfly pea (Clitoria mariana), and the introduced Dixie ticktrefoil (Desmodium tortuosum), kudzu (Pueraria montana), black locust (Robinia pseudoacacia), Chinese wisteria (Wisteria sinensis) and an assortment of other legumes.
Innate host plant preferences confer greater performance on larvae, due to differences in leaf nutrient concentrations. However, preference may be influenced by a larva’s rearing host species.
They live in meadows and swamps. Their average size is 2 inches (5 cm) long. Average life span is about 2 months. Their predators are wasps, ants, birds, frogs and spiders.
