A single-brooded species, adults fly in June and July. Caterpillars can be found between August and early October feeding on withered oak and beech leaves, either on the ground, on fallen branches, or on damaged branches still attached to the tree (1). The overwintering stage is the pupa(1).
In the UK this species occurs in a small and declining population in the Chilterns in Buckinghamshire, and in two populations in Essex (2). The range extends through most of Europe to Siberia, northern Iran and China (2).
