[2] It is differentiated from other members of the genus through a lack of anterior angles on its pronotum, the punctures on top of the head being as coarse as those on the elytra, and its first front tarsal segment being equal in length to its third.

[1] It is native to the Western Palaearctic, including Macaronesia, Cape Verde and North Africa and has been introduced into Canada.

[2] Adult beetles mate in late August on the leaves of host plants, with eggs first laid 5–10 days after copulation.

Oviposition takes place from the end of September through winter until mid-April and a single female may lay up to 1000 eggs, deposited in small clusters in the soil beneath the host plant at depths of 1–5 cm.

In central parts of Europe it has a cyclic appearance with peaks in populations at intervals of about seven years.
