EspañolTITAN BEETLE
(Redirected from Titanus giganteus)
The 'Titan beetle' (''Titanus giganteus'') is the largest known beetle in the Amazon rainforest and one of the largest insect species in the world. It is from the family Cerambycidae (longhorn beetles). The titan beetle is the only member of its own genus. It is known from the rain forests of Colombia, Ecuador, Peru, the Guianas, and north-central Brazil, where it is most commonly collected by the use of mercury-vapor lamps, to which the males are attracted.
Adults can grow up to 6.5 inches (16.7cm) in length[1] (or 8 inches (21cm) including antennae). It is said that their mandibles can snap pencils in half and cut into human flesh. Adult Titan Beetles do not feed, they simply fly around to find mates. They are attracted to bright lights after dark.
The larvae have never been found, but are thought to feed inside wood and may take several years to reach full size before they pupate. Boreholes thought to be created by titan beetle larvae seem to fit a grub over two inches wide and perhaps as much as one foot long.
The adults defend themselves by hissing in warning, and have sharp spines as well as strong jaws.
★ There is an extensive sequence towards the end of Sir David Attenborough's ''Life in the Undergrowth'' series (in the version released in the UK) which prominently features a hunt for this beetle. In it, an adult specimen was found and brought back to Oxford University. Because the adults do not eat, this specimen was cared for until it died.
★ A famous "life-size" photograph of a putative larva of this beetle appeared in National Geographic Magazine, filling an entire page, but it was of a different species of beetle, possibly ''Macrodontia cervicornis''.
★ There is a local "cottage industry" in French Guiana of leading tours specifically to collect specimens of this beetle (which can command prices over US$500), and other countries' ecotourism agencies mention these beetles in their advertisements.
