A very rare xerotherm species in the south of Belgium, nowadays only found in the province of NA where it has a small stable population in the Famenne region.
Wingspan 26-34mm. An extremely variable species in its colouration and forewing pattern, well-marked and patternless including dark en pale forms. Females are usually active at twilight and early evening, males most often at night. Both sexes come readily to light.
Hibernates as an egg or young caterpillar. The young larva feeds in bulbs and as a mature larva also on leaves. The fully grown larva can be found during May and June.
The adults fly from mid September to mid October.
