A fairly common species in most areas of Belgium, with most observations in the northern part of the country.
The adults have been observed from July till October. They are active at night and come to light or sugar.
The larvae live on the comb in bee-hives, preferably an old one, in a silk-lined gallery. They hibernate and later pupate in their cocoon.
