Here is a Black Swallowtail Butterfly caterpillar feeding on a dill plant. The day after I photographed this caterpillar on the dill, it disappeared. I thought it had either died or crawled away to pupate. Then, I found it (I think) crawling in the middle of my lawn, far from any twig to attach itself to. I gave it a lift on a stick to one of my fennel plants in case it needed a little more food. The next day I saw it had attached itself to a twig and the day after that it was a chrysalis.
