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.

White-Lined Darkling Beetle
A smooth, elongated darkling beetle with a distinctively long pronotum. It is common in the Chihuahuan and Sonoran deserts.
