we planted some bare root prairifire crabapples this spring. We have very few leaves on them and now we're finding that they're being eaten by something. On the back of one leaf I found a colony of some brown worm like creatures. No hair, didn't see legs. Really looked like worms. No webbing was noted. Any suggestions? I've tried searching catapillars, but can't find anything that matches. Anyone here in WI who has the same issue? PLEASE HELP.
