Wingspan c. 12-16mm.
This species is distributed over much of the British Isles, though it tends to be commoner in the North.
The adult males are brownish-grey with several darker spots, and females are similar, though paler. Both sexes often show a sheen to the forewings.
There are similar species however, and care must be taken with identification; dissection is often necessary for confirmation.
The early stages are poorly documented but the species occurs in dry grassy habitats and is suspected to feed on grasses or moss.
