Xixuthrus
Xixuthrus is a small genus of long-horned beetles, found primarily on Pacific islands, including Indonesia, New Guinea, the Solomon Islands, and Fiji, and contains some of the largest living insect species, the giant Fijian long-horned beetle and the Taveuni beetle. These beetles have powerful jaws, and should be handled with care when alive. No scientists have yet seen a larva of this genus, although in Fiji, where three different species occur, the natives consider them to be a rare and special delicacy.[1]
