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.”

Questionmark Caterpillar

Dear Sandra,
When attempting to identify plant feeding insects, it is tremendously helpful to know the food plant.  Thanks for informing us this Caterpillar was feeding on hops.  We quickly identified it as the caterpillar of a Questionmark butterfly thanks to BugGuide.  Here is a BugGuide image that looks even more like your individual.  The adult Questionmark is a beautiful butterfly.

Your letter to the bugman:  Hello! Hope you are both well.
It was quite exciting to discover this little caterpillar attaching itself to a Kiowa Pecan sapling after a rainstorm. I’ve been getting photos of the chrysallis each day, and seeing amazing changes daily. We’ve had multiple thunderstorms and high wind (hence the staking of the sapling, not my preference but necessary on this hilltop). Temps 60-80 degrees, gusty winds, high humidity. Dates May 1, 2, and 3.
If I were to hazard a guess, I’d say this may be a Checkered White?
Thank you for all of your help. We live next to a green space now, lots of butterflies and birds… among other various living things 😉

Checkered White Caterpillar

Hi Ellen,
How nice to hear from you.  We apologize for the delay.  Daniel is currently in Ohio for Mother’s Day and there is excruciatingly slow internet here.  We agree with you that this is a Checkered White caterpillar (see BugGuide) and chrysalis (see BugGuide).  Perhaps you will be lucky enough to witness and photograph the eclosion of the adult butterfly.

Checkered White Chrysalis

Thank you so much! I’ll continue photographing and checking the chrysalis each day. It appears to be doing well despite the ongoing rain and wind. Best wishes, and safe journey to Daniel.

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.
