A common species throughout Belgium.
Native
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.
The adults have been observed from May towards August, occasionally later. Most observations during June.
It occurs in gardens, parks, open woods, embankments and woodland edges.
