The Asian Long-Horned Beetle, the invasive pest that caused the destruction of 30,000 trees in Worcester a year ago has shown up in Boston. What’s worse, they were found near the Arnold Arboretum, one of the gems of the city.

One difference now is that they’ve been detected early, before they’ve had much of a chance to spread. In Worcester, the infestation was in full force before anyone noticed. Hopefully, they can contain this spread and mitigate the damage.

The lesson here – volunteers and experts alike fanned out throughout the city in recent weeks, looking for signs of the beetle. They were trained in what to look for and where to look, and we’re keeping our fingers crossed that it pays off.
