Specimens in nature


In late summer the larva lives as a borer in a young shoot, of which the distal part may die off. After the hibernation the larva bores in a swelling bud, the infection then is recognisable by frass that is ejected through an opening at the base of the bud. It overwinters in a hibernaculum.
The adults are active from late evening onwards and later come to light.
