The Chestnut Heath inhabits dry to damp grasslands in woods, meadows, poor grassland, calcareous grasslands, and open marshy habitats. These grasslands are sometimes quite intensively grazed, as can happen on calcareous grassland. However, if grazing is absent, for a few years, change in the grassland does not seem to affect the butterflies. The butterflies do not fly very much, and only cover limited distances. The eggs are laid one by one in short rows on the blades of grasses, such as fescues (Festuca spp.), Tor-grass (Brachypodium pinnatum), Purple Moor-grass (Molinea caerulea), Upright Brome (Bromus erectus), and Crested Dog’s-tail (Cynosurus cristatus). Pupation takes place deep down in the vegetation. The Chestnut Heath mostly has one or two generations a year, depending on altitude and latitude.
