This attractive yellow and pink moth has a wingspan of about 1 inch. The male (B & C) has large, feather-like antennae; the female’s are thread-like. The caterpillar is brown with dark brown diagonal lines on the sides. The head is small and the first 2 thoracic segments have a white line down the center. The 3rd thoracic segment is very large.


This is a common moth in Fontenelle Forest and Neale Woods. It may be seen during daylight from May through October, but most likely in late August and early September.


As its common name implies the larvae feed on chickweed, as well as smartweed, clover and other low plants.
