A little while back a reader sent us a photo of a green caterpillar in his garden. He’s found several of the green caterpillars as of late, and he was seeking more information about them. The reader has already done some research and indicated that he thought he found “tomato worms” (based on other information, we can confidently assume he meant “tomato hornworms”, which are actually caterpillars), in large part because the creatures were on his tomato plant. He was most puzzled about the webs they seemed to be spinning for themselves, and he also wondered if the “worms,” once enmeshed in a web, had died. What are these green caterpillars, if they even are caterpillars, and what’s the deal with the webs they are creating?
