This weekend a small infestation of Asian longhorned beetle (ALB) was found in Jamaica Plain (Boston). The site is at Faulkner Hospital (click to see map), just across from the Arnold Arboretum. Six infested maple trees were found so far, in close proximity to each other, and have already been removed by USDA/DCR. Surveys will continue this week.

It is extremely important that we get the word out ASAP to everyone in the Boston, Brookline, and Newton area to be on the lookout for:

1) Adult Asian longhorned beetles (shiny black beetles with white spots and long, banded antennae) – check out this handy pocket guide

2) ALB exit holes (dime-sized, perfectly round holes, especially in maple, but also in birch, elm, horsechestnut, willow and other hardwood trees…but not oak)

3) ALB egg-laying sites (divots in the bark ranging in size from 1/4 to 3/4 inches across – fresh pits often have oozing, foaming sap)

Anyone seeing anything suspicious should report it immediately at or toll-free: 1-866-702-9938. Take photos if you can.
