Description

Wing span: 24 - 27 mm

This species forms discrete colonies, some of which can be very large, containing many thousands of individuals.

In England it is almost entirely confined to south-facing chalk hills, cliffs and undercliffs between Weymouth and Swanage.

It is only found on steep south-facing downland or cliffs where the grass is allowed to grow into large clumps.

Adults are on the wing from the end of June to early September, with a peak in August. The larva is the over-wintering stage.

The larval foodplant is Tor Grass (Brachypodium pinnatum).

Adults feed on Marjoram and Scabious flowers.

Adults fly only in sunshine and fly very fast at low level. They rarely stray far from favoured breeding areas.

This species has Near-Threatened status on the UK list.
