Davey, P., 2009: A local species in southern Britain, the larva feeding on oak (Quercus spp.). In Dorset, the moth is confined to old oak/birch woodland where in favourable seasons, it is abundant. Yellowham Wood, Rooksmoor, Piddles Wood and Boys Wood are localities where the species occurs in good numbers, for example: Piddles Wood, seventy-six at MV light on 9 July 1995 (P Davey).

This species is similar to Conbathra tumidana1435. Diagnostics include: this species lacks raised scale tufts on the coloured band immediately behind the white cross line.
