The larva lives inside the stem causing a spindle-shaped gall, up to 15 mm long and 4 mm broad, mainly in the top- and side-stalks, preferably in a flowering side-stalk.
Before pupation an exit hole is made in the lower part of the gall, leaving only a thin layer of bark. The pupa lies with its head downwards in the cocoon.
The species hibernates in the adult stage.
