You might be seeing webs in trees with worms inside. The bugs are often referred to as tent worms, eastern tent caterpillars, web worms, or caterpillar worms. However, they are actually larvae, and their mother built the web to protect the growing bugs while they eat and grow. 

To know which kind of worm is invading your tree, look at where the web is located. Eastern Tent Caterpillar webs are usually found in the tree branch crotches. Web worms make their nests at the ends of the branch.
