It has a life cycle of one to two years, with adults appearing from June to August
Recorded host plant families are: Betulaceae . Another listed host is Alnus glutinosa.
IUCN lists this species as "near threatened", because its area of occupancy is unlikely to be much more than 2,000 km² and it has a severely fragmented distribution. Its habitat is very old broad-leaved trees. Such trees are declining. Hence it is thought that the population is decreasing. It is threatened additionally by the creation of transport corridors and by logging.
