I found this little guy munching on my curly parsley yesterday. There are actually 2 of them but they are on the move in my herb basket because they ate just about all the curly parsley already. The picture shows him a lot more greener than he really is. He/she is a pretty caterpillar with greenish-yellow and black stripes. I don't mind him/her eating at my herb garden as I only planted it for decorative purposes. I wanted something green between my 2 lounge chairs and thought why not try growing some herbs in a basket. Of course, the herbs have just about outgrown the basket and I intend to buy some pots to put them in separately but was just curious about this caterpillar that is munching away. Is this a monarch cat and how much does he/she need to eat? Should I just let them munch away?
