A rather scarce species in Belgium, mostly recorded in the southern part of the country.
During frost, the males don't fly and just sit immobile on tree trunks. Males come to light, females are wingless.
The adults fly from the beginning of October till the end of December but mainly between mid October and mid November. The beginning and the end of the flight period changes from year to year and depends on the weather conditions.
