It can be found in woodland, parkland, hedgerows, scrubby downland and sometimes gardens. There is one generation per year, from late July to late September. The egg is the over-wintering stage. Oaks are the main larval foodplants. Limes, Elms and probably others are also used. It comes to light, sometimes in numbers. Sightings
