Fall web worm

We always have some of these show up about this time of year, but this year it is like a plague. They really like the black walnut trees. There are so many the eat every leaf off the tree and then migrate down to the ground and crawl until they find something else they can eat. This is a young walnut in my yard about 40 feet tall.

Is that the same worm as ‘Tent’ caterpillar?

No, the tent caterpillar is a spring pest while fall webworm strikes in summer into fall. Tent cats bunch up under their tent but leave it when feeding while webworms feed under a much more expansive web. FW does more damage to trees I manage because I’m done spraying when they appear.
