Milkweed Tussock Moth - Euchaetes egle
Size: Wingspan 32-43 mm
Identification: Wings are usually unmarked and gray. The abdomen is yellow with black spots.
Range: Easter half of the US plus Quebec and Ontario.
Habitat: Fields and edges with host plant ( milkweed ).
Life Cycle: Larvæ feed on milkweed ( Asclepias sp. ). Adults are sometimes found on the host plant during the day. Females lay eggs in "rafts" and the caterpillars are gregarious during instars 1-3. They become solitary in later instars when marked with bright tufts.
May defoliate milkweed. But at least they're not pest right? ;)
