Silver-Spotted Skipper (Epargyreus clarus) lives in open grasslands across North America. It feeds on mallow plant leaves.
Fascinating facts about the Silver-Spotted Skipper
- Silver-spotted skipper caterpillars become tiny architects, building up to five leaf shelters that change style as they grow. The first cut of a shelter takes about 6 to 7 leaf segments, while the second cut needs only 2 to 4 segments and is roughly 75% the length of the first. Larvae pause for roughly 30 minutes between each cut, and the whole construction usually finishes in under two-and-a-half hours. Because they then spend about 95% of their time resting on the shelter ceiling, the structure dominates their daily routine and offers a rare glimpse into insect engineering.
- Male silver-spotted skippers stake out tiny territories about the size of a small room, perching 3.3 to 6.6 feet (1 to 2 m) above the ground on branches or tall weeds. From these lookout points they dart out at passing insects, hoping to intercept a receptive female.
- Caterpillars of the silver-spotted skipper are leaf-eating on a wide roster of legumes, from native false indigobush and American hog-peanut to introduced kudzu and Chinese wisteria. Their diet also includes groundnut, American wisteria, butterfly pea, and the invasive Dixie ticktrefoil. This broad host range lets the species thrive in diverse habitats, fields, swamps, brushy edges, by exploiting any Fabaceae plant that crops up, underscoring its adaptability to both native and disturbed landscapes.
- The adult silver-spotted skipper spans 1.75 to 2.625 inches (4.5 to 6.7 cm) across its wings. Males sport slightly more pointed forewings than females.
- The number of silver-spotted skipper generations varies dramatically across its range: one brood per year in the northern and western parts, two in the east, and three to four in the deep south.
