Habitat

When to see it

The adult flight period is from late June to August, sometimes coming to light.

Life History

The species is quite easily identified at the larval stage by its distinctive case made of rings of mined leaf, fully developed in May. The mines are large and obvious on the upper side of the leaf, betraying the larva or larvae on the lower side. Cased larvae occur from September to May, but are small until March, after the winter diapause.
