A black-and-white image of a web over a tree branchIt’s webworm season. The squirmy bugs are actually caterpillars and they can create some sticky situations in area trees.

“They develop this web around them to protect them from the birds,” Lou Meyer, a certified arborist for the The Davey Tree Expert Company, said.

He said while webworms are caterpillars and not worms, the “web” part of their name definitely describes them.

“Looks like giant spider webs, and you’ll notice that some of the leaves are gone, and that’s where the web worms are feeding on those leaves,” he said. “The webs themselves are this really high tensile strength web. It’s kind of hard to break them.”

And those webs can get rather large.
