Black Swallowtail Caterpillar

Hi Jim,
Thanks for sending us your wonderful documentation of the metamorphosis of a Black Swallowtail.  Maria Sibylla Merian would be impressed.  It appears as though the Chrysalis image is of the exuvia, the cast off skin after the butterfly has emerged.  It is also quite curious that the Chrysalis is up-side-down.  Generally the Swallowtail Butterflies make a Chrysalis that is upright and supported by the silk girdle.

The adult imago is a female.  The female has blue markings while the male has yellow spots.
