Longhorned beetle (Anoplophora spp.) is an insect pest.
The longhorn beetles are a cosmopolitan family of beetles, typically characterized by extremely long antennae, which are often as long as or longer than the beetle's body. Eggs are separately deposited in tree bark. After the beetle larvae hatches, it chews into the tree, forming a tunnel that is then used as a place for beetle pupation. Anoplophora is one genus of this family.
