Small beetle with enlarged rear legs which allow it to jump large distances. The larvae can be a problem in brassica crops such as canola where they develop inside the stems.

Flea beetle is a general name applied to the small, jumping beetles of the leaf beetle family, Chrysomelidae. Two differing viewpoints hold that flea beetles are either a distinct subfamily, the Alticinae, or that they make up the tribe Alticini, which is a part of the subfamily Galerucinae.
