Titan Beetle

• récordIt is one of the largest beetles in the world, and its jaws are strong enough to snap a wooden pencil in two.
• The adults do not feed: they live off reserves built up during the larval stage and seek only to breed during the few weeks left to them.
• Its larva has never been found in the wild; it is assumed to develop over years inside dead trunks underground, but it remains a mystery.
• The largest reliably measured individual had a body length of 16.7 cm, not counting horns: by body alone it is larger than the Hercules beetle, whose horn takes up half its total length.
• The adult eats nothing at all: it emerges with the reserves it built up as a larva and spends them looking for a mate.
• The larva has never been found. Its size is inferred from the exit holes in the wood, which would fit a grub more than five centimetres across.
• The famous life-size photograph of a supposed larva published by National Geographic turned out to be of another species, probably Macrodontia cervicornis.
• Its mandibles snap a pencil in half, and the animal hisses in warning before it bites.

Skeleton type

Invertebrate - chitin exoskeleton (insect)

Habitat and environment

Humid Amazon rainforest, around large dead trees

Sexual maturity

The adult emerges, does not eat and lives around 14 days on its larval reserves; the males patrol trunks and fallen trees in search of female pheromones

Gestation / incubation

The larva of Titanus has never been found and is not scientifically described. It is assumed to bore through large-diameter dead wood for several years before pupating, but neither the development period nor the way of life is known; the only host plant cited in the literature is Siparuna pachyantha

Best time: It is seen almost exclusively at night, drawn to powerful lights in lowland Amazonian forest; its range covers Colombia, Guyana, French Guiana, Suriname, Peru, Ecuador, Bolivia, Venezuela and northern Brazil
