This is quite an attractive beetle with bright metallic bluish-green elytra (wing cases) which are strongly punctured with tiny holes. The head is dark metallic blue to black, and the thorax and legs are toffee coloured. It is very similar to Oulema melanopus, and separation via genitalia dissection is usually necessary to distinguish the species. Length 4 to 6mm.
The adults and larvae feed on grasses and may cause damage to cereal crops, and may be considered a pest species.
Seen April to September, and found in grassy places. Common and widespread in the southern half of Britain.
