In China, this species may have a one or two year life cycle, depending on the geographical region. The egg, larva, or pupa can overwinter.

Asian Longhorned Beetles
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.
Male Female Adult Female. Adults are drawn to recently felled, stressed, or apparently healthy hardwood trees. Hosts include healthy maple, horse chestnut, birch, Rose of Sharon, poplar, willow, elm, locust, mulberry, chinaberry, apple, cherry, pear, and citrus trees. It may also attack other species of hardwood trees. In addition, nursery stock, logs, green lumber, firewood, stumps, roots, branches, and debris of a half an inch or more in diameter are subject to infestation.
