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.
Golden Tortoise Beetle
Looks like a tiny golden jewel. Can change color from gold to reddish-brown by controlling moisture in microscopic layers of its shell. Color changes with stress or mating.
Did You Know?
The golden tortoise beetle can change color from brilliant gold to dull red in minutes by controlling fluid in nanoscale layers of its shell — like a living mood ring.
