Davey, P., 2009: A local species that is restricted to south-east Britain, the larva feeding on the leaves of elm (Ulmus spp.) and less often on other deciduous tree species. In Dorset, the moth is local, and unlike its elm-feeding cousins, has managed to survive the Dutch elm disease epidemic. This may be because the species colonises elm growing as hedgerow and as young trees that develop infectable corky bark only when they mature, so the disease passes them by in the early stages of their growth. Distinct colonies have been discovered over recent years at Holnest, Alners Gorse, Woolland, Povington Wood, Tatton Coppice, Motcombe, Gillingham, Shapwick and Gaunts Common. The moth together with Lesser-spotted Pinion2316 and White-spotted Pinion2317, was present about fifty years ago in coastal suburban areas in vice county 11, although it was rated as uncommon.

This species is similar to Lesser-spotted Pinion2316. Diagnostics include: cross-lines are black with minimal white, not solely white; the bend in main outer crossline is curved, not right-angled; ground colour reddish, not tawny or brown.
