I didn't get a very good shot of the back of the caterpillar for two reasons:
(1) the lid of the fish tank was in the way of getting a good shot, and
(2) the kids were right at my elbow

This shot is not very clear, but you can see that the chrysalis is beginning to form from the bottom up. It is actually just like a shedding of the skin on a snake. Here the chrysalis is halway there.
