A species with few records in the past, but since the recent quest for leafmining species it seems to be fairly common.
The adults fly in one or perhaps two generations a year. Moths have been seen from June towards early September.
The yellowish larva makes a long brown gallery beneath the bark on a young twig of Cytisus scoparius, generally close to the tip. Pupation in a dark ochreous brown cocoon.
