Lasiommata megera is a common resident. Nevertheless, the Dutch Monitoring Scheme shows that the species is undergoing a moderate decline; in 2003, its numbers were only a tenth of those of 1992. It usually flies in two generations from mid-May until the end of August and hibernates as a half-grown caterpillar. Several species of grass serve as larval foodplant. The butterflies seem to prefer a short, mosaic vegetation with patches of bare or nearly bare ground. They are mostly found on grassland situated on roadside verges, dykes, along hedgerows or at the edge of woodland.
