Swallowtail. Pipevine Caterpillar, Day 13. Gainesville, Florida. 2013.
I hope this isn't getting tiring, but here's another caterpillar shot. They're growing quickly now and are about 1/2 an inch long. The caterpillars have scattered and I can only find about 5 of the 16 or so that I've been following, but that doesn't necessarily mean that they've been eaten. In fact, the pipevine that they feed on is toxic, so it gives them some protection. They're in their 3rd instar. 2 more, then to chrysalis. I am hopeful that I'll see at least a few of them through to butterflies!
