Dasychira grisefacta [Lymantriidae]

Dense covering of white, grey, and black hairs of varying lengths, including thick tufts of grey hairs in A1-A4; a pair of long tufts of black hairs project forward laterally from A1 and backward laterally from A8; also a single tuft of long black hairs projects backward dorsally from A8; clusters of short white clubbed hairs occur dorsally and laterally; bright red glands middorsal on A6 and A7; a row of single long, black, clubbed hairs point laterally. This species is uncommon and feeds on conifers such as Douglas-fir, during April and May. This caterpillar is similar in appearance to Dasychira vagans but differs in having a row of single long black, clubbed hairs that point laterally.
