The images below provide a visual reference to the distinct physical characteristics, evidence, and lifecycle of the Asian longhorned beetle. Click on the thumbnail below to view a larger image.

Asian longhorned beetle (ALB) egg oviposition site. The adult beetle chews a small notch in the bark of a tree and then lays an egg just under the bark.

Once hatched, the egg becomes a larva. Larvae bore into the tree, where they feed on the vascular layer.

A larva becomes a pupa. Pupae remain inside the tree until they become adults.

A pupa becomes an adult ALB. Adults bore their way out of the tree, creating exit holes.

Adults ALBs emerge from late spring to early fall and feed on tree bark and tender twigs.

Adult ALBs usually stay on or nearby the tree on which they were born.
