Arge ochropus (Gmelin, 1790)

Arge ochropus

One of the black and yellow species. A. ochropus can be separated from Arge pagana by the yellow pronotum and tegulae and yellow legs with black rings on the apices of the tibiae and tarsi. In Arge pagana these body parts are suffused with black. Athalia spp. are often misidentified as this species.
Larvae feed on roses and are difficult to separate from Arge pagana larvae.
