The underside of the beetle has a coppery colour, and its upper side is sometimes bronze, copper, violet, blue/black, or grey.

They can be found among roses on warm sunny days from May until June or July, and occasionally as late as September.

They can also be found in South East Asia, in the countryside and outlying islands of Hong Kong.

The larvae are C–shaped and have a firm, wrinkled, hairy body, a small head, and tiny legs.

The larvae overwinter wherever they have been feeding, which may be in compost, manure, leaf mould, or rotting wood.
