Asian Longhorned Beetle
An Unwanted Invasive Species
The Asian longhorned beetle (ALHB, Anoplophora glabripennis) is a highly destructive wood-boring pest of maples and other hardwood trees including poplar, birch and willow. ALHB infests and kills healthy trees, devastating urban and rural communities.
Adult beetles are 20-35 mm long, shiny black, with up to 20 white spots on each wing cover.
Signs and symptoms of this pest include:
ALHB is native to Asia and can be introduced into Canada with infested wood packaging material (e.g. wooden pallets, crates, boxes, etc.). Once in a new environment, ALHB can disperse naturally or spread long-distance through transport of infested wood products including firewood and logs.

- Check tree for evidence of ALHB
- Collect suspect ALHB specimens, if found
