Description
Scarites buparius reach a length of about 35–40 millimetres (1.4–1.6 in), with a maximum of 60 millimetres (2.4 in). The basic black color of this glossy beetle is aposematic, highlighting clearly the body on the sandy substrate.
Elytra present thin and shallow striae, almost absent in larger specimen. Sexual dimorphism is not conspicuous, but females are usually slightly smaller than females and the mandibles of the males are longer and hooked.
The males use their impressive mandibles to fight each other. This intra-male aggressive behaviour consist of a repeated series of fighting events, during which a dominance/submission status is established. The attack behaviour persistence is correlated with the body length. During the fights the males grab the head of the antagonists and rise them into the air. These fights sometimes end with the death of one of the contenders.
