The Red-winged Wave (Dasyfidonia avuncularia
) is a colorful day-flying moth, occasionally mistaken for a butterfly when flying. The forewing is chocolate brown with a whitish submarginal shade, and black postmedial, antemedial and median lines. The hindwing is bright reddish orange with two bold black transverse lines and fine black striations. The wingspan is about 25 mm (Anweiler and Schmidt 2003).
The larvae are red-brown with shades of pink and have a broken yellow spiracular band (Powell and Opler 2009).
The immature stages are undescribed (Anweiler and Schmidt 2003). Adults are diurnal with a single flight from early April through early July (Powell and Opler 2009).
The Red-winged Wave is found in open conifer forests and sagebrush habitats (Powell and Opler 2009).
The larvae feed on Prunus
leaves. Adults nectar at flowers including those of Ceanothus
and Prunus (Powell and Opler 2009).
