Mecynorhina torquata
Mecynorhina torquata is a beetle from the subfamily Cetoniinae, tribe Goliathini. Description
Mecynorhina torquata is among the largest flower beetles in the world, only surpassed by the goliath beetles. It reaches about  of length in the males, while the females are slightly smaller, reaching  about  of length. The basic colour is green with whitish markings on the elytra. The males have a horn in the forehead. The larvae can reach about  of length in the males, with a weight of about 30-40g. Distribution
These beetles are native to tropical Africa, especially in the Democratic Republic of the Congo, Cameroon and Uganda. Research 
Cyborgs of M. torquata have been created by implanting electrodes and a radio device. By sending radio signals to make the electrodes stimulate the muscles, it is possible to control the beetle's walking and flight. Subspecies
