The moth flies in one generation from the end of March to mid-May. Larva pale or dark blue grey; dorsal and subdorsal lines yellow; the sides black with a yellow spiracular line, marked with a white spot on each segment; head whitish with coarse blackish mottling. When young they feed gregariously mainly on oak (Quercus) in a silken web, but later separate. The larvae feed also on various other trees and shrubs.

The wingspan is 31–36 mm. The length of the forewings is 15–17 mm. Forewing sandy rufous, black speckled, median area generally deeper rufous: lines browner, edged with pale, the outer dentate lunulate; stigmata with yellowish outlines and grey centres: submarginal line rufous and yellowish: hindwing white, rosy tinged along the termen; cellspot, outer line, and veins sometimes well-marked. Form rubricosa Esper is the form in which the red of the median area is most emphasised. Form pallida Tutt is greyish ochreous, with hardly a vestige of rufous: in virgata Tutt, while the basal and marginal areas are grey, the median space is rufous.
