Brief SummaryRead full entry
The Scarce Heath occurs in damp to wet grassy meadows in or at the edges of woods. Sometimes, they occur away from woods in drier places or in flower-rich grassland. The butterflies are fond of settling in grass and do not fly far, nor very often. Among the grasses they use as food are Tufted Hair-grass (Deschampsia cespitosa) and Bearded Couch (Elymus caninus). When half-grown, the caterpillar hibernates in a grass tussock, later also pupating there. This species has one generation a year. Habitats: humid grasslands and tall herb communities (26%), mixed woodland (19%), broad-leaved deciduous forests (14%), mesophile grasslands (9%), fens, transition mires and springs (7%).
