A very rare and local species in Belgium, not often recorded. Onwards from 2020 more and more observations became known.
Hibernates as a pupa in a tough cocoon among leaf litter.
The adults are easily flushed by day from leaf litter. They come to light and sugar.
The adults fly in one generation a year: from mid April till beginning of July.
The larva lives on Quercus, preferring the young shoots of coppice stools.
