The ALB’s primary diet is maple trees but has also been found in many other tree species. Maple trees are one of the dominant tree species in our forests.
The ALB is a real and imminent threat to Michigan forests. The ALB has been found in the surrounding states of Michigan. This invasive beetle has not yet been found in Michigan. Since insects do not respect state lines, it is a real possibility the ALB is already here.
Because ALB has not yet been found in Michigan, it is important to monitor your trees and self-educate in identifying the invasive insect as well as learning to distinguish it from its native look-a-like, the white spotted sawyer beetle. Other states have had to remove many trees already. If we catch the infestation early, it may be easier to manage.
