Note the beetle's size and describe the identifying characters. It is advisable to retain the specimen in case further checks are needed.


Almost any habitat, in winter retreating into grass tussocks, under loose bark or amongst fallen leaves.

When to see it

Throughout the year.

Life History

It does indeed feed on both peas and beans in gardens but only in a very minor way and causes very little damage to the crop. As an adult, this small creature feeds on the leaves of many leguminous species including Red and White Clover although for some reason it avoids Lupins. The larvae feed on the roots of the same species under the soil.
