Tiger Swallowtail Caterpillar

Dear Crystal,
This is the caterpillar of a Tiger Swallowtail butterfly.  There are several species in your area, and our best guess is that this is the Eastern Tiger Swallowtail,
Papilio glaucus.  Here is a BugGuide image for comparison.  The adult Eastern Tiger Swallowtail is a gorgeous butterfly.

Orange Dog

Dear Laura,
This is the Caterpillar of a Giant Swallowtail, commonly called an Orange Dog.  It will eat some leaves, but it will not negatively affect the health of your tree.  Unless there are hundreds of them or the tree is very very small, the tree can stand to lose a few leaves.

Common Mime Caterpillar

Dear Carlos,
This caterpillar is quite colorful, but alas, we have not had any luck with an identification.  Perhaps one of our readers will have better luck.

Update:  June 11, 2019
Thanks to a comment from Karl, we now know that this is a Common Mime Caterpillar, Chilasa [Papilio] clytia.  According to Butterflies of Singapore:  “Across the range where this species occurs, the early stages feed on leaves of serveral plants in the Lauraceae family. The sole recorded local host plant, Cinnamomum iners (Common name: Clover Cinnamon, Wild Cinnamon), is a very common plant all over Singapore, readily found in nature reserves, gardens, parks and wastelands etc. It is a small to medium-sized tree with 3-nerved leaves. Eggs and early stages of the Common Mime are typically found on saplings at heights from knee to waist level.”

Your letter to the bugman:  Can you tell us what this is before we leave the state? Have lived in Florida for 17 years and have seen some strange bugs but this one takes the cake.
Thanks

Orange Dog

Dear Dennis,
This is the Caterpillar of a Giant Swallowtail, commonly called an Orange Dog because they feed on the leaves of orange trees and other citrus.

Your letter to the bugman:  This is currently on my lime tree and not moving.  I thought it was a butterfly but the head looks like a lizard or snake.

Orange Dog

That’s ok!  I found it!  It’s a skull caterpillar! A Very cool bug indeed.
Rita
I love that you get so many photos of weird bugs that you cannot answer them all.

Dear Rita,
We are not certain where you found the name “Skull Caterpillar” but we do know that Orange Dog is a commonly used name for the caterpillar of the Giant Swallowtail.  The markings on the Orange Dog, which feeds on the leaves of orange trees and other members of the citrus family, are thought to mimic bird dropping for protection.

Very interesting, thank you:)
I got the term skull caterpillar from a google search.
Sincerely,
Rita

Swallowtail Chrysalis

Dear Amber,
Most butterflies have a chrysalis that hangs downward from the tip of the abdomen from a silken button spun by the caterpillar, but most Swallowtail caterpillars have an upright chrysalis that is also supported by a silken girdle.  Your chrysalis looks like a Swallowtail Butterfly chrysalis, but we are not certain of the species.
