The rhinoceros beetle, aka horn beetle or unicorn beetle, is part of the scarab beetle family (Scarabaeidae). These are the largest known family of beetles in the world. They can also be found on every continent, sans Antarctica. Rhinoceros beetles may look big and scary, but they’re actually quite peaceful… to humans. However, when males encounter each other the gloves come off. Their IUCN status varies per species and are too vast to name. For more information on the largest of the known rhino beetles, check out my article on the Hercules beetle.
First the Stats…

Now on to the Facts!
1.) There are over 1,500 species and 225 genera of rhinoceros beetles described to date.
2.) Most rhino beetles are nocturnal (active at night).
3.) Their only defense against predators is to bury in the substrate or fly away.
4.) When threatened they also emit a loud hissing sound. This sound is produced by rubbing their wing cases against their abdomens.
5.) Adults feast on plant sap, nectar, and fruit. Even though they’re large, they don’t eat much. The larvae, on the other hand, eat tons. They feed on rotting wood or compost.
