Species Ceresa basalis

The usual color form is greenish on top, black below, but often the rest of the body is very dark also. The dark legs and underside, and brown patches on the sides of the pronotum, are distinctive. It has much shorter "horns" than other brown Ceresa such as C. diceros, and they are also less widely spaced. [based on comments from Andy Hamilton]

Willow

Common in the north.

Ceresa diceros has much longer horns, more widely spaced.

Unusually dark specimens of Ceresa palmeri may have all-brown legs.
