Black-and-Red Froghopper

The male of Cercopis vulnerata is 8.9–10.5 millimetres (0.35–0.41 in) in length, and the female 8.2–10.5 millimetres (0.32–0.41 in). These froghoppers have an elongate and strongly shielded body. They are shining black, with bright red marks on the elytra, one triangular mark at the base, one square mark in the middle and a stripe at the apex. These colors serves as a warning of their unpleasant taste.

The hind wings are brownish, smoky and translucent. Upper abdomen is black with narrow red stripes at the rear extremities of the tergites.

This species is very similar to Cercopis sanguinolenta, but its red markings are larger and the rear stripe is U-shaped. Other rather similar species are Cercopis intermedia and Haematoloma dorsata.
