I want to thank all of the people who responded to my post asking what this little guy was. I am now the proud mom of a Black Swallowtail caterpillar who seems to love my curly parsley. I have a few pots on this poor old deck and how it got there I didn't get the chance to see but wow ! I am very glad .. now my question is does it spend the winter in a cocoon in this pot ? .. I need to know so I won't dump the pot .. heaven knows I may have done THAT for years without a clue that there was a special life living on the plant .. yikes !!!!
