The larva first lives as a miner in the stem of the foodplant. It moves into the roots just before winter and hibernates there. In spring it returns to the stem where it makes galleries in the lower portion and it also mines the leaves.
When full-grown it pupates in the final mine in a pale ochreous cocoon.
The species hibernates in the larval stage.
Adults hide during daytime. They become active at night and come to light.
