what is it?

The eastern tent caterpillar ( Malacosoma americanum ) is a species of moth in the family Lasiocampidae, the tent caterpillars or lappet moths. It is univoltine, producing one generation per year. It is a tent caterpillar, a social species that forms communal nests in the branches of trees. It is sometimes confused with the gypsy moth and the fall webworm, and may be erroneously referred to as a bagworm, which is the common name applied to unrelated caterpillars...
