The harlequin beetle (Acrocinus longimanus) is a large and distinctly colored species of longhorn beetle from the Neotropics and the only member of the genus Acrocinus.
It is given its English name because of the elaborate pattern of black, orange-red and greenish-yellow markings in both sexes; despite this the beetle is quite well-camouflaged when perched on a lichen or fungus covered tree trunk. The species name longimanus is a Latin word that refers to the extremely long forelegs (manus) of the large males, which are longer than the beetle's entire body. The head-and-body of this beetle measures 4.3 to 7.5 cm (1.7–3.0 in) long. The size and unusual appearance of the harlequin beetle has made it popular among insect collectors. Although essentially harmless to humans, it may bite in self-defense with its strong mandibles.
