The Large Heath or Common Ringlet (Coenonympha tullia) is a butterfly in the family Nymphalidae. It flies in variety of grassy habitats, including roadsides, woodland edges and clearings, prairies, bogs, and arctic and alpine taiga and tundra. It is a poor flyer, but can sometimes be found along ditches seeking new grounds. It is common to northern Europe and Asia and across North America. A butterfly is a mainly day-flying insect of the order Lepidoptera, the butterflies and moths. Like other holometabolous insects, the butterfly's life cycle consists of four parts: egg, larva, pupa and adult. Most species are diurnal.
