Life cycle

Larvae: August-June.  Adults: June-August.  The larva initially feeds inside a flower, sealing the entrance and overwintering within.  In spring it feeds inside the tip of a new shoot and later on leaves, making distinct holes.  Finally it chews halfway through a stem, causing the upper part of the plant to wither. and feeds on the tip of the withered part.
