Family: Skippers (Hesperiidae)
Subfamily: Spread-wing Skippers (Pyrginae )
Identification: Wings are brown-black; hindwing is lobed. Forewing has transparent gold spots; underside of hindwing has a metallic silver band.
Wing span: 1 3/4 - 2 5/8 inches (4.5 - 6.7 cm)
Life history: Adults perch upside down under leaves at night and on hot or cloudy days. To seek females males perch on branches and tall weeds, and occasionally patrol. Females lay single eggs near the host trees, and the caterpillars must find their proper host. Young caterpillars live in a folded leaf shelter; older ones live in a nest of silked-together leaves. Chrysalids hibernate.
Habitat: Disturbed and open woods, foothill streamcourses, prairie waterways.
