Who's been eating my cabbage?

Well actually, it is their cabbage. I planted it just for the caterpillars to eat because they turn into the small white butterflies that are known misleadingly in North America as Cabbage Moths. I also have parsley planted in hopes of getting monarch caterpillars. I heard this is supposed to work very well locally but so far nothing. In any case, my garden is quite filled with lovely white butterflies flitting around and laying more eggs on their cabbage plants.
