Winter Moth information:  

    • This past winter was atypically warm, but most nights were below freezing temperatures.
    • Researchers at UMass Amherst speculate that winter moth eggs could hatch as early as the third week of March, when the host trees could still have very tight buds so the caterpillars could not enter, feed and cause damage.
    • Winter moth eggs become powdery-blue as the embryo develops, and turn very deep blue-black just before hatching.
    • Conditions will vary because of the localized climate effects on both winter moth eggs and host plants.
