Grey Chi Antitype chi

(Linnaeus, 1758)

Wingspan 32-37 mm.

A predominantly northern species, being commonest in central and north-west England and Wales, but occurring locally in southern England. It is locally common in Scotland and Ireland.

The single generation flies in August and September, when it comes to light. The adults like to rest on walls and rocks, where they can be very inconspicuous.

Moorland and grassy hillsides are the preferred habitats, and the larvae feed on a number of low-growing plants and shrubs.
