Distribution – Restricted to south-east England from Hampshire in the west up to Suffolk, where it is scarce. Isolated records from Wiltshire, Cornwall, Worcestershire and Nottinghamshire.

Biology – The larvae develop in soil, feeding on the roots of a range of grass species. Imago insects emerge in late-May and are present until July. Male insects are more conspicuous, resting on grass stems and flying in the evening and at night, sometimes being attracted to artificial light. The females are more elusive, often staying at ground level.

Habitat – Primarily calcareous grassland, but also any dry grassland areas and gardens.
