About Arge cyanocrocea (Forster, 1771)
Adults of Arge cyanocrocea reach a length of 7–8 millimetres, or 0.28–0.31 inches. Like all sawflies, this species is related to wasps rather than flies, and it does not have the narrow constricted waist that is typical of wasps. Its head and thorax are black, while its abdomen is yellowish orange. Its legs are reddish with small black rings. The wings have a distinctive wide transverse dark band and a gray apex. Arge cyanocrocea is quite similar in appearance to Arge pagana, which has solid black wings. This sawfly species can be found across most of Europe, the Caucasus, Asia Minor, and Japan.
