Looks like this is a caterpillar infestation, perhaps a fall webworm.

It looks like this occurred some time ago and the larvae have already left. You may be able to see leaves with obvious chewing damage, some droppings from the larvae, or perhaps a larvae that died in the web. There may be other webs in the vicinity that still have active larvae.
