Harlequin beetle

The harlequin beetle (Acrocinus longimanus) is a large tropical longhorned beetle native to the Americas, especially from southern Mexico to Brazil in South America.[1] The harlequin beetle feeds on sap and is given this name because of its elaborate pattern of black, red and greenish yellow markings on the wing covers of both sexes.[2] The species name longimanus is a Latin word that makes reference to the extremely long forelegs (manus) of the males, which are usually longer than the beetle’s entire body. As an adult, the species is very large, with a body that can measure nearly 76 mm (3 inches) in length.[3] It also famous for carrying pseudoscorpions.

Not to be confused with harlequin cabbage bug (Murgantia histrionica).
