How big is the titan beetle?

If you think your phone is big, wait until you see the titan beetle. This insect is the largest known beetle in the world, and one of the largest insects overall. The largest specimen ever measured was 6.5 inches (16.5 cm) long. That’s longer than an iPhone 13 Pro Max!

The titan beetle belongs to the family of longhorn beetles, which have long antennae and cylindrical bodies. But unlike most longhorn beetles, the titan beetle does not have horns or projections on its head or thorax. Its body is reddish brown and covered with fine hairs.

The titan beetle is so big that it can snap pencils in half and cut into human flesh with its powerful jaws. It also has sharp spines on its legs and thorax to deter predators. But don’t worry, the titan beetle is not aggressive and only bites when threatened.

Where does the titan beetle live?

The titan beetle lives in the rain forests of South America, mainly in Colombia, Ecuador, Peru, Bolivia, Brazil, and the Guianas. It prefers humid and warm habitats with plenty of trees.

The titan beetle is a rare sight, as it spends most of its life as a larva underground or inside wood. The adult beetles only emerge for a few weeks to mate and die. They do not feed at all as adults, relying on the energy stored from their larval stage.

The male beetles can fly and are attracted to light sources at night, while the female beetles are flightless and stay hidden in the vegetation. The male beetles use pheromones to find the females and mate with them.

What are the titan beetle’s secrets?

The most mysterious thing about the titan beetle is its larval stage. No one has ever seen or collected a titan beetle larva in the wild. Scientists only have some clues from boreholes found in wood that are thought to be made by the larvae.

The larvae are estimated to be over a foot long and feed on decaying wood below the ground. They may take several years to reach full size before they pupate and emerge as adults. Some people have claimed to have seen or photographed titan beetle larvae, but none of these claims have been verified by experts.

The titan beetle is one of the most fascinating insects on earth, but also one of the most elusive. We still have much to learn about its life cycle, behavior, ecology, and evolution. Maybe one day we will discover its secrets and marvel at its wonders.
