Nationally scarce (Nb) in coniferous woodland, plantations and gardens in parts of Britain. In Hampshire formerly locally common amongst spruce, especially in young plantations, but recorded recently only from Botley Wood, Havant Thicket and Micheldever Wood. Not recorded from the Isle of Wight to date. Wingspan 12-14 mm. The strongly biciliate-fasciculate antenna of the male and in both sexes the pure white area of the hindwing, together with the lack of a developed ocellus in the forewing, distinguish
E. pygmaeana from
E. subsequana [Bradley]. Larva feeds on Norway Spruce, living between needles spun together with silk, over-wintering as a pupa.
