Davey, P., 2009: A common species in England and Wales, more local in Scotland, the larva feeding on a variety of deciduous tree and shrub species. In Dorset, the moth is common in deciduous woodland and occasional to frequent elsewhere. There are no records of the species being trapped on Portland to date. The peak of the second brood is nearly three times larger than that of the first. The national norm is for two generations in southern Britain, but in Dorset, occasional third generation moths are observed during the autumn. The period between each brood peak is roughly one hundred and twelve days.

Hill, L., 2014: Ectropis bistortata (Goeze) is now considered a specific synonym of E. crepuscularia ([D. & S.]) (Agassiz et al, 2013).
