The little glassywing skipper iis in the Subfamily: Grass Skippers (Hesperiinae).
The little glassywing has a series of translucent, distinct white spots on both of the surfaces of the forewing. The largest central spot which is just below the stigma of the male is elongated with the corresponding spot on the female being square. The hind wing beneath often has a faint purplish or rusty gloss and there is usually an indistinct band of pale spots. The little glassywing has a white area on the antenna just below the club. Its wingspan is 1 1/16 - 1 1/2 inches (2.7 - 3.9 cm). U.S.A. range Range: Central New England west to central Nebraska; south to northern Florida, the Gulf Coast and South Cenral Texas close to moist places near shaded wood edges.
Adults feed on the nectar from pink, white and purple flowers including joe-pye weed, dogbane, selfheal, peppermint and swamp and common milkweeds. The one I have pictured preferred hummingbird sage, Texas sage, scarlet sage 'Coral Nymph' (Salvia coccinea). Yellow flowers are visited when others are unavailable. Caterpillar hosts include purpletop (Tridens flavus) which is common in old fields and open woodlands. Its inflorescence is purple and often covered with an oily substance which explains other common names such as "soapgrass and "greasegrass". The caterpillars eat leaves and live in shelters of rolled leaves.
