Hi,
No, this is not a stuffed toy! Found this 1 1/2″ critter on my patio in Galveston, Texas 2 days ago. I did not touch it but my neighbor’s young daughter put in her hand and it was crawling around in her hand. Any idea what it could be??

Spicebush Swallowtail Caterpillar

Spicebush Swallowtail Caterpillar

Dear Lonnie,
This is a Spicebush Swallowtail Caterpillar.  The adult Spicebush Swallowtail is a large black butterfly with colorful spots and “tails” on its underwings.

Daniel,
Thank you so much, this was driving me crazy!! Glad to hear it is a butterfly as this is my first year to raise and release the Monarch butterfly.
Thank you again

They seem to be stationary over 2 days, they seem not to have even moved
I am an arborist and found them on a young ash tree, could they be feeding on the sap?
They are about 2 inches or 5 cm long and the photo taken in late October 2016

Swallowtail Chrysalis

Swallowtail Chrysalis

Dear Richard,
This is the Chrysalis of a Swallowtail Butterfly in the genus
Papilio.  Since you are an arborist and you were able to identify the tree, we suspect this is the Chrysalis of a Pale Swallowtail, a species with a caterpillar that feeds on the leaves of Ash and other trees, and that ranges in your area.  According to BugGuide:  “Larvae feed on foliage of woody plants in several families: Rosaceae (cherry, e.g., Prunus emarginata, Holly-leaved Cherry, Prunus ilicifolia), Rhamnaceae (California Coffee-berry, Rhamnus californica, Ceanothus spp.), Oleaceae (ash, Fraxinus) and Betulaceae. Overwinters as pupa, adults emerge in spring. Males seek hilltops for mating.”  Based on the BugGuide information, you will have to wait for spring to see the adult Pale Swallowtail emerge.

Thank you so much for your fast reply
Kind Regards

Two-Tailed Swallowtail Caterpillar

Two-Tailed Swallowtail Caterpillar

This is one of the Tiger Swallowtail Caterpillars, and there are several different species with similar looking caterpillars found in Arizona.  Since you were able to provide the food plant, the ash tree, we have determined that this is a Two-Tailed Swallowtail Caterpillar, Papilio multicaudata, and we verified the food plant on Butterflies and Moths of North America.

Hi there. I have found a few of these on my lime tree. I was wondering what they are and what type of moth/butterfly they will become.
I live in Sunningdale, Cape Town. It’s October now and it’s the first time I have ever seen them.
When touched they produce a forked shaped protrusion from their head and secrete a clear liquid. They are still quite small and I’ve only found three so far.

Citrus Swallowtail Caterpillars

Citrus Swallowtail Caterpillars

Dear Tamlyn,
These are Citrus Swallowtail Caterpillars, and there are several species that go by that common name.  We found this matching image on Alamy, but it is not identified to the species level.  
Papilio demodocus is one species called a Citrus Swallowtail, and it is pictured on BioDiversity Explorer, but there are no early instar caterpillars pictured. We also located a matching image on iSpot.

Swallowtail Chrysalis

Swallowtail Chrysalis

Hi Amy,
It was nice meeting you in the photography class at Glendale Community College.  This is the Chrysalis of a Swallowtail Butterfly in the genus
Papilio.  The Swallowtails produce a chrysalis that is held upright with a silken girdle.  We believe the most likely candidates are Giant Swallowtail, Anise Swallowtail and Western Tiger Swallowtail.  If you could give us some idea of what plants were growing near the sighting, we might be able to narrow down the species.

Tiger Swallowtail Caterpillar

Probably Tiger Swallowtail Caterpillar

Dear Finbar,
While your caterpillar looks very similar to the link to our archives you cited, your Tiger Swallowtail caterpillar is most likely the originally described Eastern species,
Papilio glaucus.  While the appearances of the caterpillars of the three different Eastern species, we concede that you might have encountered an Appalacian Tiger Swallowtail caterpillar as you are within the BugGuide listed sightings, though there are no actual Virginia sightings.  You are a little too far south to likely be the Canadian Tiger Swallowtail, which BugGuide reports only documented sightings considerably north of you, with the closest being Pennsylvania.
