Beaver Rove Beetle

A tiny, dark aleocharine rove beetle that inhabits the nests of beavers and other semi-aquatic rodents. It feeds on organic debris and invertebrates in the warm, humid nest environment.

💡

Did You Know?

This nidicolous beetle has adapted to the unique microclimate of beaver lodges, where humidity is near 100 percent and temperatures remain stable year-round.

Queenless Ponerine Ant

A large black ponerine ant found across South and Southeast Asia that lacks a morphological queen caste. Instead, a single mated worker called a gamergate monopolizes reproduction.

💡

Did You Know?

The gamergate maintains her dominance by mutilating the gemmae of newly emerged workers, preventing them from mating.
