In areas where Gorse is present.
The adult stage lasts from August to April. It hibernates over winter and can reappear in the early spring. The larvae feed from late May to early August on Gorse and Greenweed from obvious silk tubes as thick as a pencil.
Widely but locally distributed throughout the British Isles, it can be locally common among gorse in coastal localities. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local.
Rarely recorded in Leicestershire and Rutland.
