I believe that is a black swallowtail caterpillar. I read somewhere that gardener should plant some parsley for yourself, and some for the butterflies!
I did get the horns to appear, but this guy smells of parsley.

Is that a Swallowtail caterpillar. Did you know that if you tickle his head yellow horns come out and they smell of pineapple...of course this is probably of no interest to you at all :-)
