Prefers coastal habitats but it can be found locally throughout most of Britain.
Usually a late flight period from July through to early November but can be seen earlier.
The larvae feed on mosses on walls and in sand-dunes.
Mainly coastal but often encountered inland. In the Butterfly Conservation’s Microlepidoptera Report 2011 this species was classified as common.
Occasional in Leicestershire and Rutland. L&R Moth Group status = C (very scarce resident or rare migrant). This species seems to be becoming more common in our area.
