Pipevine Swallowtail Chrysalis - Battus philenor

Pipevine Swallowtail Chrysalis - Battus philenor
Parkwood, Durham County, North Carolina, USA
May 27, 2004
Fresh chrysalis, shortly after skin of last instar caterpillar was shed.

The catepillar was wild, raised naturally on cultivated Aristolochia serpentaria in my garden. Several caterpillars were captured in their final stages and put into an enclosure with sticks for pupation. Some of this group emerged in two weeks or so. One chrysalis (brown), overwintered and emerged on May 10, 2005, almost one year after pupation.
