A small but robust, reddish or purplish brown moth with rather blunt wings named after an eminent 19th century entomologist. An obvious whitish kidney mark has two whitish streaks running to the outer edge of the wings.

The males often fly at speed in sunshine, especially in the afternoons and at dusk. They can be seen visiting the flowers of Ragwort, Knapweed and Heather. Flies again at dusk and into the night.

    In southern parts of its range its main habitats are fens and wet heaths, but further north it is a species characteristic of upland acid moors and mosses.

    • Not at all common in southern Britain, occurring sparsely in East Anglia, Hampshire, south-west England, south Wales, and most of the Midlands. Somewhat commoner further north, in North Wales, northern England, the Isle of Man and Scotland as far as the Orkneys, Hebrides and Shetland. Occasional in Ireland.
