Are longicorn beetles beneficial or harmful?
Longicorn beetles are pests. Cerambycidae is short for Insecta, Coleoptera and Cerambycidae. Anoplophora longicorn larvae eat wood, form irregular holes in the wood, and excrete powdered feces. Wood is valuable to human beings, and the performance and appearance of wood eaten by longicorn beetles will be greatly reduced, reducing its commercialization, so longicorn beetles are pests to human beings.
