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.
