What is Spongy Moth?
Spongy Moth, formally known as Gypsy Moth, is an invasive species has causes damage in its caterpillar phase by chewing on leaves to the point of defoliation of entire forests.
Spongy Moth was purposely introduced in 1869 with the intent to be used for silk production. Soon after, moths escaped. Eradication efforts were made but failed. States in the northeast, mid-Atlantic, mid-western, and central Appalachian all have established populations.
Natural dispersion is slow. Many new populations are started after items such as patio furniture or firewood, with egg masses on them, are moved
