Neocrepidodera ferruginea
European rusted flea beetle, Altise ferrugineuse européenne
Neocrepidodera ferruginea is a flea beetle in the family Chrysomelidae, native to Europe and introduced to North America. Adults are brown in color and feed on a variety of herbaceous plants, particularly grasses and composites. The species inhabits meadows and grasslands, and has been recorded from numerous host plants including Poaceae, Asteraceae, and various weeds. Larvae develop within roots and central stems of host plants. In North America, it was first documented in Ontario and Québec in the 1970s and has since spread northeastward, where it is considered a potential agricultural pest.
