Okay, not really worms....I know they're caterpillars of some sort. I'm not a vegetable gardener and so these are new to me, but I'm sure that someone on the NE Forum will recognize them.
I found these two on parsley that I went to pick for tonight's dinner. This parsley grows in a pot on my deck. And right above the parsley is a birdhouse, occupied by a pair of house wrens with hungry babies that they're feeding. Maybe the wrens don't like these?
Thanks for any information,
