Thank you for your report! That's not Spongy moth (=AKA "gypsy moth"), which doesn't make webs that cover the leaves. Those webs are made by the native Fall Webworm, Hyphantria cunea. Although the webs are unsightly, the caterpillars rarely defoliate trees. Insecticide treatments are not advised, because the caterpillars are protected by their webbing. Webs can be cut from the tree and destroyed. The moth is very common and lays eggs on a variety of trees.
