Winter moth adults will appear in large numbers around lights over the next few weeks. Many areas have already seen winter moth adults. These adults mate and the females lay eggs in the barks of trees they will attack. The eggs hatch in early spring, with the larva climbing up into the canopy to consume the leaf tissue of the infested tree. Our plant health care services includes winter moth treatments. Work is underway in Massachusetts to implement some biological control measures.
The University of Massachusetts Cooperative Extension is looking for reports of Winter Moth, so please report activity if you see winter moth this fall at this link to the Massachusetts Winter Moth Survey.
