Hercules Beetle
The species most people picture first. Males carry an enormous thoracic horn that can make up nearly half their total length, yet they're calm and easy to handle. Larvae are slow, large, and need a long, well-fed development period — patience is the whole game here.

Rainbow Stag Beetle
