Hello WTB! Love your site. Attached is a couple pictures of what I believe to be a Giant Swallowtail caterpillar. I hope you can find use for it.

Orange Dog

Hi Simon,
The larvae of Giant Swallowtails are commonly called Orange Dogs because they feed on the leaves of citrus trees, including orange trees.  Your caterpillar is an early instar, meaning is still will undergo several molts before transforming into a chrysalis.  Giant Swallowtail Caterpillars are easily overlooked by predators because they resemble bird droppings.

Thank you! And yes, it was on an orange tree =-)
