This year my parsley is being eaten by small caterpillars that are stripped black and green with orange spots that come out like antennae when you aggrivate the caterpillar. I keep on picking off the caterpillars and throwing them on the grass. I figure something laid eggs in the soil since it is in a pot and this did not happen last year.

If you throw them on the grass they will just crawl back onto your parsley.

Not necessarily........if there are holes in the bottom of the pot, for drainage, they can crawl in through there.

Like CH said, I hope you are killing them b/4 you toss them onto the grass..........if not, probably pulling off the same one!
