Species of beetle
From Wikipedia, the free encyclopedia
Trigonopterus oblongus is a weevil found in Papua.[1] It was notable as the first known instance of a biological screw joint.[2] The weevils are just 4 millimetres (0.16 in) long and can fold their legs below their body. The biological screw joint is just 0.5 millimetres (0.020 in) in size.[3][4] This discovery was made by Alexander Riedel of the State Museum of Natural History Karlsruhe and by Thomas van de Kamp of the Karlsruhe Institute of Technology .[3]
