Camouflaged Black Swallowtail Butterfly Caterpillar in the fennel patch

"There is nothing about a caterpillar that tells you it's going to be a butterfly." -Buckminster Fuller (of Buckyball fame, etc.)

The fennel is the fine-leaved plant with the yellow florets. (The broad-leaved plant is, I believe, Russian Tarragon.) Isn't it cool how the green & black stripes and yellow dots on the Black Swallowtail caterpillar help it blend in with the flowering fennel plants and avoid the notice of hungry predators?
