Asian long-horned beetle ALHB is an invasive forest pest with no natural enemies in North America that attacks nearly all broadleaf trees, with native Maples being the preferred host. Adults lay their eggs in hardwood trees, and larvae then tunnel through the living tissue of the tree stopping the flow of water and nutrients, killing it. There have been very few sightings of ALHB in Ontario and it is important to be on the lookout for this dangerous invader. Several native non-harmful beetles can be easily confused with ALHB, so take a close look at how to identify this beetle listed below. Asian long-horned beetle is native to China and Korea where it is considered a major pest causing mortality of Elm, Maple, Poplar and Willow trees.

Native to parts of Asia, the beetle is believed to have arrived in North America in the wooden packing material used in cargo shipments from China. In all instances where Asian Long-horned Beetles have been found, authorities have reacted quickly to stop the infestation from spreading. Trees favored by the Asian Long-horned Beetle are predominantly maples, but infestations have also been discovered in horse chestnuts, poplars, willows, elms, mulberries, black locusts, and many other varieties. They are shiny and black with white spots and have long antennae that are banded black and white. These beetles have wings and can fly, although only for short distances because of their size and weight. Continued feeding causes structural defects in the tree and eventually kills the life-sustaining cambial layer by girdling. Mature beetles then burrow out of the tree, leaving holes the diameter of ball-point pens.
