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.
Birch Bark Beetle
A small, dark brown bark beetle that infests birch trees in boreal and subarctic forests. Adults bore through bark to create characteristic gallery patterns. Outbreaks can kill weakened birch trees over large areas.
Did You Know?
The gallery patterns carved by this beetle's larvae under birch bark resemble ornate branching designs that are unique to the species.
