Davey, P., 2009: A local species in the British Isles, the larva feeding for two years on the roots of bracken (Pteridium aquilinum). The adult male is said to exude a scent reminiscent of pineapple. In Dorset, the moth is rather local, preferring the shelter of woodland on acid and clay soils where bracken abounds. The oscillating dusk flight of this species has been observed by the author immediately above bracken canopy in Chase Woods, in Holt Wood and close to Hardy's monument on the summit of Black Down in June and early July.
