Wingspan about 11 mm. 

Often encountered near to buildings.

Adult moths are on the wing between late May and August.

The larvae feed on mosses during the spring.

Having a somewhat disjunct distribution in Britain, this moth occurs in many of the southern English counties, and then is rather scattered northwards to Northumberland. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as Nationally Scarce A.

Rare or under recorded in Leicestershire and Rutland. The Wigston record of 14th May 2017 is the first for VC55.
