Which northeastern US states are specifically noted for having a concentrated presence of the Winter Moth?

Answer

Massachusetts, Maine, and New Hampshire

The documentation explicitly highlights that the known distribution of the Winter Moth is highly concentrated in the northeastern United States. Specific states frequently mentioned in reports where organizations track the insect's presence and impact on local ecosystems include Massachusetts, where agencies monitor its activity, Maine, whose Department of Agriculture, Conservation and Forestry issues health reports concerning its presence in woodlands, and New Hampshire, where it is listed among damaging insects requiring attention from residents and arborists. These three states form the key area of concern detailed for forest health agencies in that region.
