Choristoneura
Choristoneura is a type of moth that can be found in many places. They have beautiful wings and are important for nature because they help pollinate flowers.
生息地: Forests
The Choristoneura moth has mottled wings, typically grey-brown with darker spots or bands, which form a bell-shape when at rest. Its body is stout and covered in fine hairs. This camouflage helps it blend seamlessly with tree bark.
