Bionomics

The larva starts in the tip of a shoot which it aborts, causing a swelling, recognisable because the frass is ejected as a light coloured lump. It hibernates in the stem and pupates in a flimsy cocoon, close to an already prepared exit opening in the lower part of the stem.The part of the plant above the gall often ultimately dies off.
The adults are active at dusk and later come to light.
