Hercules beetle
The Hercules beetle, belonging to the rhinoceros beetle subfamily Dynastinae, is recognized as one of the largest beetles in the world, reaching lengths of nearly seven inches (17 centimeters). Native to the rainforests of Central and South America, this impressive insect is distinguished by its horn-like appendages on both its head and thorax, which resemble the structure of a rhinoceros's horn. The Hercules beetle is not only known for its size but also its strength, a trait that connects it to the mythological Greek hero, Hercules.
These beetles are primarily herbivorous, feeding on plant matter and sap while navigating the bark of trees. Their body is segmented into three main parts: the head, thorax, and abdomen, with antennae for sensing their environment and elytra that serve to protect their delicate wings. Mating occurs in the spring, with male beetles often engaging in battles for females. After mating, females lay eggs in tree bark, and the larvae undergo several developmental stages, including a hibernation period, before emerging as adults with an average lifespan of about 34 months.

Hercules beetle
The Hercules beetle is the largest of the rhinoceros beetle subfamily Dynastinae. They are called rhinoceros beetles for the large horn-like appendages on their heads and thorax, or middle section. The Hercules beetle is known for its incredible size and strength. Hercules was a Greek mythological character known for his strength.

The Hercules beetle lives in the rainforests of Central and South America. As an insect that feeds on plant matter and sap, the Hercules beetle is typically found climbing along the bark of trees. It is one of the largest flying insects in the world.
The rhinoceros beetle is a large insect with unusual horn-like appendages on its head and thorax, or mid-body section. The horn on the Hercules beetle's head is curved upward and touches the downward-curving horn from the insect's thorax near the middle of the long, extending appendage. These horn-like appendages are what give the Hercules beetle the name rhinoceros.
Growing to nearly seven inches (17 centimeters), the Hercules beetle is one of the world's largest beetles. Like other beetles, the body of the Hercules beetle is divided into three main parts—head, thorax, and abdomen, or lower section. Beneath the large, horn-like appendages on the Hercules beetle's head are this insect's antennae. The Hercules beetle uses its antennae to help it sense smells in its environment.
Over the abdomen of the Hercules beetle are this insect's wings. Its front pair of wings appears in the shape of hard cases known as elytra. The elytra cover and protect the delicate rear wings of the Hercules beetle. When the Hercules beetle crawls with its six legs, its elytra appear as a solid, speckled green piece of exoskeleton, or external skeleton. When it flies, the elytra lift, and the rear wings flutter and flap, carrying the beetle into the air. During takeoff, the elytra of the Hercules beetle serve much the same purpose as the construction of wings on an airplane.
Mating season for the Hercules beetle occurs in the spring. Male Hercules beetles may fight over a female. The males ram one another with their horn-like appendages until one wins and the other dies. The victorious male mates with the female. After mating, the female lays her eggs in holes in the tree bark. The eggs hatch into small, worm-like beetle larvae after one month. They remain in this stage until the weather gets cooler. They then crawl into holes and hibernate, or rest for the winter. As they rest, their bodies continue to change and develop. They pupate in the spring, or move into their final developmental stage, lasting two to three months. They molt, or shed, their skins a final time and emerge as adult Hercules beetles.
The average life span for the Hercules beetle is 34 months. It spends most of its life as a larva.
