Reunion Flightless Weevil
A flightless weevil with fused elytra endemic to the island of Reunion. Its inability to fly has made it vulnerable to habitat fragmentation.
Did You Know?
Flightlessness evolved independently in many island beetle lineages as an adaptation to windy conditions.
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.
