Occupying a range of grassy and open areas  especially where bracken is present.

The adults fly in June and July, from dusk onwards.

The female deposits the eggs in flight, and the larvae feed on bracken (Pteridium aquilinum), mainly internally until fully grown, when they feed on young shoots.

Locally distributed throughout Britain and Ireland. In a recent survey to determine the status of all macro moths in Britain this species was classified as local.

Scarce / uncommon in VC55.
