Birch Leaf-Roller Sawfly
A flat-bodied sawfly with long, thread-like antennae and a broad abdomen. Larvae roll birch leaves into tubes using silk and feed inside these shelters.
Did You Know?
The larva creates an elaborate rolled-leaf shelter that protects it from both predators and weather while it feeds inside.
Metallic Eumolpine Beetle
A brilliant metallic dark blue to violet beetle closely related to the North American dogbane beetles. It is found on vincetoxicum and other Asclepiadaceae in the mountains of Europe.
Did You Know?
Like its North American relatives on milkweed, it sequesters toxic cardiac glycosides from its host plant to deter predators.
