A not so common species in Belgium, hitherto almost only known from the northern part.
The larva starts in the tip of a shoot which it aborts, causing a swelling.
It hibernates in the stem and pupates in the lower part of the stem.
The images are active at dusk and later come to light.
The adults have been observed from early June till mid July.
