Balcanocerus provancheri

Appearance

A very distinctive species, dark brown overall with bold yellow markings. The head is pale, with two bold black spots on the margin. The pronotum has a pale spot on either side of a broad pale midline. There is a very broad yellow patch on the clavus (upper portion of the wings), bordered by black, and a pale rectangular spot on the costa of the wings; otherwise, the wings are smoky brown. While adults are typically cinnamon brown, some individuals can be bluish to black: 1, 2. The male subgenital plates are elongate and narrow. The female pregenital sternite is strongly, roundedly produced on the posterior margin with no notches. Adults are 4.5-5.5 mm long. Nymphs are ant-mimics and range in color from red to black (same as ants).
