Davey, P., 2009: A rare species restricted to bogs in south-east Britain, the larva feeding on sedges (Carex spp.). In Dorset, the moth is confined exclusively to mire habitat where it is at low density; it is on the wing at the height of the summer between mid-July and mid-August. Three sedge species tend to be present in the vicinity of colonies. These are: common yellow sedge (Carex viridula oedocarpa), carnation sedge (Carex panicea) and star sedge (Carex echinata).
The following light trap records indicate dispersal on occasion: Wyke Regis, on 6 August 2006 (D Foot), Puddletown, on 18 July 2005 (H Wood Homer). Conservation agencies who manage sites containing mire habitat, for example, Morden Bog and Hartland Moor (Natural England) and Parley Heath (Herpetological Conservation Trust) should include this species in their management plans.
