Rajah Naga Stag Beetle
A medium-sized stag beetle with reddish-brown elytra and a black head bearing distinctly toothed mandibles. Males display significant size variation with mandible shape changing allometrically.

Small males have straight, simple mandibles while large males develop elaborate curved and toothed mandibles, a phenomenon called male dimorphism.

A striking metallic green stag beetle from South American cloud forests. Males have elongated mandibles with tooth-like projections.
Did You Know?
Its brilliant metallic green coloration is caused by microscopic structures in the exoskeleton rather than pigments.
