My parsley plant proved to be a haven for butterflies again. This time I was prepared to keep the little guys (and/or gals) safe. I bought a butterfly enclosure so that once the caterpillars were big enough, I could keep them hidden from birds. Four caterpillars cocooned and one so far has become a butterfly. The other three are still there but I don't know if they have died or if they are waiting until the spring to emerge.
