DESCRIPTION: An elongated, reddish-brown bug, 15–20 mm long. The edge of abdomen is flat with white and brown bands. The antennae consist of four elongated segments.

STATUS: Widespread throughout Europe including in Slovenia.
SIMILAR SPECIES: Similar include the box bug (Gonocerus acuteangulatus), Ceraleptus gracilicornis and other European bug species although none of these have the broadened leaf-like tibia on their hind legs.ariety of natural habitats, farmland and urban areas as well as tree-plantations.
