Known for its massive horns, the Hercules beetle is one of the longest species of beetles on our planet1. You will only find these longhorns in male Hercules beetles, which they use to fight other males when looking for a mate. 

This horn also accounts for more than half of the male Hercules beetle, bringing them to a length of up to 7 inches. You can find Hercules beetles in Central and South America rainforests and the Caribbean islands.
