The Small Heath is an inconspicuous butterfly that flies only in sunshine and rarely settles more than a metre above the ground. Its wings are always kept closed when at rest. Underside of forewing has eyespot at tip. Hindwing banded with brown, grey and cream. The number of broods and the flight periods are variable and adults may be seen continuously from late April to September on some sites in southern England.
This relatively widespread butterfly can occupy a range of habitat types and, although its range has changed little, many colonies have disappeared in recent decades. Widespread in Britain and Ireland.
