Violet Dung Beetle
A small, distinctive dung beetle with a flattened body and yellowish elytra marked with dark spots. Despite being in the tunneler group, it shows some dweller-like behavior. Commonly found at cattle dung in African grasslands.
Did You Know?
This species makes its brood balls inside the dung pat itself rather than in tunnels, blurring the line between tunneler and dweller strategies.
Ponderous Borer
One of the largest cerambycids in North America, this prionine breeds in the roots and lower trunks of dead ponderosa pines. Adults are dark brown with a somewhat rough body surface. They are nocturnal and attracted to lights.
Did You Know?
Larval development can take up to six years in dry dead wood, one of the longest development times for any beetle.
