The Northern Wall Brown is found in woodland clearings and meadows in woodland, usually in relatively warm places with large rockmasses. The butterflies are fond of basking in the sun on warm rocks or on the ground. The eggs are laid on a number of grasses, including fescues (Festuca spp.), small-reeds (Calamagrostis spp.), and cock’s-foot (Dactylus spp.). The Northern Wall Brown hibernates either in the last larval instar, or as a pupa, and has one brood a year.
