The elephant beetle (Megasoma elephas) is a fascinating insect. It belongs to a group of beetles called rhinoceros beetles. These amazing creatures are found in warm, tropical parts of the Americas. They are known for their impressive size and the large "horns" that males have.

What Do Elephant Beetles Look Like?
Elephant beetles are usually black. Their bodies are covered with tiny, fine hairs. These hairs are especially thick on their wing covers, called elytra. The hairs often give the beetle a yellowish color.
Male elephant beetles have two large horns. One horn sticks out from their head, and another from their upper body (called the prothorax). The longest horn on their head looks a bit like an elephant's trunk, which is how they got their name! Females do not have these horns. Males use their horns to defend themselves and to compete with other males for food and mates.
How Big Are These Beetles?
Elephant beetles are quite large. They typically grow to be about 7 to 12 centimeters (2.75 to 4.75 inches) long. The biggest male ever recorded was 13.7 centimeters long, including its horn!
Where Do Elephant Beetles Live?
You can find elephant beetles in the warm, wet rainforests of southern Mexico, Central America, and South America. They thrive in these lush environments.
The Elephant Beetle's Life Cycle
The life of an elephant beetle begins as an egg. Female elephant beetles lay their eggs inside large, decaying logs or in the ground. After about three weeks, the eggs hatch.
The hatched eggs become C-shaped larvae, also known as grubs. These grubs are white with brown heads and six legs. They spend a long time, around 29 months, eating organic matter inside the decaying wood. This helps them grow big and strong.
After the larval stage, the grub changes into a pupal stage. This stage lasts about five weeks if the temperature is around 26 degrees Celsius. Finally, the pupa transforms into an adult elephant beetle. Adult elephant beetles live for about one to three months.
There are also different types, or subspecies, of elephant beetles. Two known ones are Megasoma elephas elephas and Megasoma elephas iijimai.
What Do Elephant Beetles Eat?
Elephant beetles have a special diet. They mostly eat the sap (the liquid inside trees) from certain trees. They also enjoy eating ripened fruits that have fallen to the ground. If they are kept in captivity, they might also eat exotic fruits like pineapples, longan, and lychee fruit. They can also nibble on the bark of some trees, like the poinciana.
Living in the Rainforest: Behavior and Conservation
Elephant beetles are creatures of the night! They live in rainforests and are most active after the sun goes down. Even when the air gets cooler at night, they can keep their bodies warm while they search for food.
Sadly, the number of elephant beetles has been decreasing. This is mainly because their rainforest homes are being destroyed. When rainforests are cut down, these beetles lose their places to live, find food, and lay their eggs. It's important to protect rainforests to help these amazing insects survive.
