''Aphis craccivora'', variously known as the cowpea aphid, groundnut aphid or black legume aphid, is a true bug in the family ''Aphididae''.〔(【引用サイトリンク】title=ITIS standard report - ''Aphis craccivora'' (Koch, 1854) )〕 Originally of probable Palearctic origin, it is now an invasive species of cosmopolitan distribution. ==Description== ''Aphis craccivora'' is a small species of aphid. The female has a glossy black or dark brown body with a prominent cauda (tail-like protrusion), and legs in some shade of brown or yellow. The antennae have six segments and these and the limb segments, cauda and cornicles are pale proximally (close to the body) and dark distally (further from the body). The adults do not have wax on their dorsal surface but the nymphs are lightly dusted with wax. Winged females are up to long and have cross-barring on the abdomen. Wingless females are a little smaller.〔
