Davey, P., 2009: A local species in the British Isles, the larva feeding for two years on the roots of bracken (Pteridium aquilinum). The moth has been recorded from areas of bracken within a single locality in Dorset, Batcombe Down, where it was first discovered by J Astley in 1998. The habitat is unimproved chalk grassland. Further colonies may be discovered on leached chalky soil summits where bracken occurs. This 'Swift' is on the wing at the same time as the Common Swift.
