Orange Dog

What is this?
October 16, 2009
We found this on a dwarf orange tree in our yard today (October 16, 2009) and would like to know what it is. It had apparently eaten half a leaf in the morning. In the evening it was on another leaf, which it had begun to consume. It move it’s head vertically when I first moved my hand toward the leaf upon which it perched. We would love to know what it is. Thank you!

Orange Dog

Dear Dr. TJ,
This is an Orange Dog, the caterpillar of the spectacular Giant Swallowtail.  We gladly sacrifice a few leaves on our citrus trees to be able to enjoy this beautiful butterfly in our garden.  The resemblance of the Orange Dog to bird droppings is a camouflage mimicry device.

Swallowtail Caterpillars: Black or Anise Swallowtails???

i can has parsley?
September 14, 2009
I was at my Grandmother’s today and I grabbed a quick shot of these guys chowing down.  I believe I’ve correctly identified them via your site (because your description specifically mentions parsley!)
I hope you like this group shot of what I believe are Anise Swallowtail Caterpillars.

swallowtail cats casey 300x220 Swallowtail Caterpillars:  Black or Anise Swallowtails???

Black Swallowtail Caterpillars? or Anise Swallowtail Caterpillars???

Hi Casey,
Since you did not provide a location, we are not certain if these are Black Swallowtails or Anise Swallowtails.  The caterpillars look very similar and both will feed on parsley.  If you live in the central to eastern states, these are Black Swallowtails.  If you are west of the Rocky Mountains, they are Anise Swallowtails.

Thanks.
I live in Georgia so they would be Black Swallowtails.
Thanks guys.

Dear not sure,
This is a Swallowtail Butterfly Caterpillar “in the ‘ Pyrrhosticta ‘ group of Papilio swallowtails — P. cleotas ,P. garamas ,P. victorinus , etc.
” as previously identified on our site by Keith Wolfe.  The red horns are a defense organ known as the osmetrium that releases an odor some predators find offensive.

Anise Swallowtail Caterpillar

Bander caterpillar, Golden Gate Park, San Francisco

Hi. I found this gorgeous caterpillar hanging on to a stalk of poison hemlock yesterday in Golden Gate Park, San Francisco yesterday. (It’s August first today.) I’m dying to know what kind of butterfly or moth it will become.
Thanks

Anise Swallowtail Caterpillar

Hi Harvey,
This is an Anise Swallowtail Caterpillar, Papilio zelicaon.  The caterpillars are generally found on sweet fennel (Foeniculum vulgare) which is an introduced plant.  It is also found on carrot tops and parsley in the home garden.  According to Charles Hogue in his book, Insects of the Los Angeles Basin, “Before the introduction of these foreign plants, the larvae fed on various native umbellifers, such a Lamotium, Heracleum, and Tauschia species.”  We have never heard of them feeding on Poison Hemlock, Conium maculatum, but as it is in the same family, Apiaceae, as the other plants, this is not unusual.

Tiger Swallowtail Caterpillar

Dear bug finder,
You have found the caterpillar of a Tiger Swallowtail, Papilio glaucus.  BugGuide has an image of this typically green caterpillar with the same coloration as yours, and there is a comment that judging by the color, it is ready to pupate.
BugGuide also indicates:  “Caterpillars feed on Sweet Bay (Magnolia virginiana), Black Cherry (Prunus serotina), Swamp Bay(Persea palustris) and Tuliptree (Liriodendron tulipifera). Adults take nectar from a variety of flowers.“  The adult butterfly is typically a large showing yellow tailed butterfly with black stripes, though there are some dark females.

Unknown Butterfly Chrysalis

Green Swallowtail Chrysalis??
Mon, Jun 1, 2009 at 7:12 PM
Dear Bugman,
Thanks so much for your amazing site!! Yours is a favorite around here!
My husband accidentally washed this Chrysalis off of one of our children’s outdoor toys today. After visiting your site it looked like a some sort of swallowtail, but I haven’t seen such a beautiful green one before. He didn’t see it until after it was washed off so I don’t know if it was right side up , held with a girdle or upside down.
Also is there any way we can save it? It was undamaged and I have been very gentle in my handling of it.
It’s June st today, we live in southern central Washington State in a wooded area at about 200 ft. As you can see the chrysalis is about 1.5 inches long.
Thank you so much, Heidi

mystery chrysalis heidi 300x195 Unknown Butterfly Chrysalis

Mystery Chrysalis, probably Swallowtail

Dear Heidi,
The main distinguishing feature of a Swallowtail Chrysalis is the silken girdle that keeps the pupa upright. Since this Chrysalis has been dislodged, it if impossible for us to be certain if the girdle was present. That said, we are not certain that this is a Swallowtail Chrysalis, but it is definitely a butterfly and not a moth. If the Chrysalis is undamaged, it may “hatch” and regarding color, the color of a Chrysalis changes as the metamorphosis occurs. We would love to hear back if and when this Chrysalis hatches , especially if you can provide images of the butterfly.

Hi Daniel,
Sometimes when I log in, type a comment, and then click “Post”, a message states that my words are awaiting approval.  More often, like today, I see no such affirmation, which leads me to suspect that my two comments went into a black hole.  Thus, I’m also sending them to you directly – hope that’s OK.
Cheers,
Keith

Hi Heidi,
Your beautiful chrysalis is most likely that of the Pale Tiger Swallowtail (Papilio eurymedon) – please see http://www.utahlepsociety.org/peurymedon.html – though Western (P. rutulus) and Two-tailed (P. multicaudata) tiger swallowtails have very similar pupae and are thus possibilities.  According to Bob Pyle’s The Butterflies of Cascadia, 2002: “In the northwest, the hostplants are chiefly species of Ceanothus (buckbrush, mountain balm, mountain lilac) east of the Cascades, red alder and cascara on the west side;  ocean spray, serviceberry, and bittercherry are also used, and we observed oviposition and reared it on hardhack (Douglas spiraea).”  Do any of these shrubs/trees grow on your property?  I hope the butterfly emerges OK . . . even better if your family can watch it do so (typically in the morning).  Good luck!
Best wishes,
Keith Wolfe

Swallowtail Caterpillar from Mexico

This may be a caterpillar known as “cara de nino” in Central Mexico
Mon, Jun 1, 2009 at 5:28 AM
I have been trying to find out more about this insect for quite a while, but don’t even know where to start. I only saw one of them while living in Guadalajara, Mexico. I have been told that it is a caterpillar that pests avocado trees. It is, well, avocado green with darker lines zigzagging its oval-shape body. Its head is eerily round and shiny. Some say it has a forked, red tongue, which comes out of its mannequin-looking mouth. They are called “cara de nino” (baby face) bugs.

Pipevine Swallowtail Caterpillar

Caterpillar found in Norther California
Tue, May 26, 2009 at 3:04 PM
Hello,
My son brought home this caterpillar from a close by river. We still have it in his bug catcher with some leaves and other foliage from there and it has since cocooned.
I am curious as to what this is.
Thank you!
