Asian Longhorned Beetles

Be on the lookout! Spread the word… 

Be on the lookout for signs of damage to your trees caused by Asian Longhorned Beetles (ALB). These insects are shiny black in color with white spots and long antennae (longer than their bodies). They have already infested trees throughout the Brookline and Jamaica Plain area and may be spreading throughout the Greater Boston area. Beetle larvae may be present in your trees for a few years before the beetles themselves are visible. Their presence can be observed through the appearance of round boreholes about the size of a dime in the bark of the tree.
