Irregular Weevil
A flightless alpine weevil found on exposed mountain slopes. Adults emerge in summer to feed on low-growing alpine cushion plants.
Did You Know?
Its inability to fly has led to high genetic divergence between neighboring mountain ranges.
Broad-Horned Onitis
A large, dark brown to black tunneler with massive forelegs in males. The prothorax is greatly enlarged. It digs deep vertical shafts beneath cattle dung and is primarily nocturnal. Males use their forelegs in combat.

The enormous forelegs of the male serve double duty, used both for digging and for grappling with rival males.
