Dasychira grisefacta [Lymantriidae]


JPG-Dasychira grisefacta

Females are wingless. The male wingspan is 4.2 cm. Forewing is light gray to black with a small white subanal spot in the postmedian area. This lymantriid is usually uncommon but widely distributed in western North America. Moths fly in mid to late summer. Caterpillars feed on the foliage of species of Pinaceae, particularly Douglas-fir (Pseudotsuga menziesii) and grand fir (Abies grandis).

Similar species: Dasychira vagans wings light gray and without a subanal white spot, caterpillars are generalist feeders on foliage of flowering trees, particularly oak (Quercus) and maple (Acer); species of Gluphisia have banded markings on the forewing and no subanal spot.
