Gastrophysa polygoni L Polygonum leaf beetle

This often abundant beetle is associated with Polygonum aviculare and is not normally a pest. However, the adults sometimes move into adjacent crops, including bean and beet, to cause slight but insignificant damage; in continental Europe, the beetles are sometimes reported as pests of buckwheat. The beetles frequently rest on leaves of cereals, especially on weedy headlands, and are then often mistaken for cereal leaf beetles, Oulema melanopa (p. 145). Adults are 3.5-4.5 mm long, with a bright, metallic-blue head and thorax, purplish-black elytra and mainly orange legs and antennae; they are broader and more rounded in outline than adults of Oulema.
