Epinotia demarniana

Wingspan around 14 mm.

E. demarniana inhabits woodland, heathland and damper habitats such as fens and bogs.

The adult moths fly in a single generation during June and July, when they can be attracted to light.

The larvae feed within the catkins of birch, alder and goat willow, and then pupate on the ground in a cocoon amongst leaf litter.

Distributed rather locally in the southern and eastern parts of England, with a few records from Wales. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local.

Fairly frequent but not common in Leicestershire and Rutland. L&R Moth Group status = B (scarce resident or restricted distribution or regular migrant).
