Over all length 4 - 5mm. An orange/brown beetle with a transverse groove across the pronotum. The elytra are finely punctured in a random pattern, whereas in the very similar S. ferruginea the punctures are in neat longitudinal rows. This is a type of Flea Beetle and can suddenly spring away when disturbed.
Normally associated with thistles and sometimes Meadowsweet. The adults and larvae are thought to feed on thistles and the adults also pollen.
