Without the horn, their body length is about 3 inches. They primarily feed on wood and fruit.
3. Goliath Beetles
Goliath Beetles (Goliathus spp.) are among the heaviest insects, with males reaching up to 4 inches and females around 2 to 3 inches.
They are native to the tropical forests of Africa.
Their larvae can weigh up to 3.5 ounces, and they have six legs with sharp claws, allowing them to climb trees efficiently.

Their bodies are covered in fine yellow hairs, giving them a golden tinge.
6. Wallace’s Long-horn Beetle
While not bulky, the Wallace’s Long-horn Beetle (Batocera wallacei) is the world’s longest beetle, primarily because of its massive antennae, reaching up to 10.5 inches.
They are found in New Guinea, parts of Indonesia, and Australia.
7. Actaeon Beetle
The Actaeon Beetle (Megasoma actaeon) is one of the heaviest insects, with larvae weighing nearly 8.5 ounces.
Males can range from 2 to 5 inches in size and have long horn-like protrusions, making up a significant portion of their body length. They are native to South America.
8. Giraffe Stag Beetle
The Giraffe Stag Beetle (Prosopocoilus giraffa) is the largest member of the stag beetle family, reaching up to 4.7 inches.
