Tent caterpillars.

Some leaf-feeders fold or roll leaves together with silk to form shelters. Others chew on leaves beneath a canopy of silk, creating "nests"in foliage, mine trails within the leaf, or feed out in the open. Moderate damage to leaves can often be tolerated, but severe defoliation may cause dieback, lead to sunburn, or kill small plants.
