I was just down at the in-laws on Lake Conway and noticed small round green balls (just larger than a pin head) dropping out of their trees. I also noticed that on the ground that there were several caterpillar like worms crawling. According to the in-laws, the news just did an article on the caterpillars and their neighbor said that the dropping things was caterpillar poop. Is there anything to this? I know the bream loved the caterpillars.
