Empty Monarch Chrysalis (Silk, Cremaster, Abdominal Segments) - Danaus plexippus

Here's a neat trick - you can tell if the chrysalis is a male or female by looking at the area below the cremaster (black 'stick' attached to silk). If there is a vertical line between/underneath the bottom two black dots, then the chrysalis has a female monarch. This one has that vertical line and thus was a female.
