Crepidodera ferruginea Scopoli Wheat flea beetle

Larvae of this flea beetle are associated with grasses and various weeds, and are often common in established leys. If infested pasture is ploughed-up and subsequently drilled with wheat or other cereal crop, the larvae may transfer to the new hosts. The larvae bore into the central shoots, each leaving a minute entry hole in the base; infested shoots eventually turn yellow (Plate 3e). Symptoms are usually most evident in spring and are superficially similar to those caused by shoot-mining dipterous larvae, such as wheat bulb fly, Delia coarctata, p. 197 (q.v.).
