Arctic Weevil

A small, dark, flightless weevil with a short broad snout and rough-textured elytra. Adults are nocturnal and hide under stones during the day. Larvae feed on plant roots in tundra soil.

💡

Did You Know?

Being flightless, this weevil relies entirely on walking to disperse, which means isolated Arctic populations can be genetically distinct.

Giant Amazonian Cricket

A large burrowing cricket with a disproportionately large head and powerful mandibles used for excavating deep soil burrows. It is nocturnal and emerges at night to forage for plant material. Males produce a loud, resonant chirp from their burrow entrances.

💡

Did You Know?

Its burrowing activities help aerate tropical soils, playing an ecological role similar to earthworms in temperate regions.
