Broken Silverdrop
Epargyreus exadeus (Cramer, 1779)
Family: Hesperiidae
Subfamily: Eudaminae
Identification: Wings are dark brown. Forewing has small separate amber spots. Hindwing with small separate silver spots and an obscure pale postmedian line.
Wing Span: 1 15/16 - 2 7/16 inches (4.9 - 6.2 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.

Management Needs: None reported.
