The first generation larva lives in the stem, usually in the flowering part, causing a gall or swelling. Larvae of the second generation live in a seedpod. There can be several galls in one stem and even several larvae in one gall.
The full-grown larva chews out a neat hole in the side of the gall and leaves the gall in order to pupate amongst detritus on the ground in a white, sometimes sticky cocoon.
