A common species throughout Belgium. The most widespread and commonest of the three Epirrita species.
larva lives on a variety of trees and shrubs. Hibernates as an egg, laid near buds on twigs.
adults fly from late September till November. They are
attracted to light and occasionally to sugar.
specimens are best identified by reference to the genitalia, but characteristic
individuals are identified by; the discal spot (vaguely oval or short
vertical dash) is frequently obscure and indistinct. Normally it
touches or merges with a projection from the irregular inner edge of
the post-median fascia, which at this point resembles a figure 3 shape.
Sometimes when the discal spot is clear of the fascia, the latter is
not noticeably curved or angled around it.
