Tiger Swallowtail Caterpillar

Tiger Swallowtail Caterpillar

Dear Poppy’s,
This is one of the Tiger Swallowtail Caterpillars, and based on your location, our best guesses are either a Pale Tiger Swallowtail Caterpillar (see image on BugGuide) or a Western Tiger Swallowtail (see Bugguide for image).  The orange coloration indicates that this individual is nearing the time to metamorphose into a chrysalis.

Hi again. I will have two id requests today, if you don’t mind. This is my first;
I was out in the garden photographing bugs (I have recently discovered the world of macro photography). Around the porch area, I found a bird thingy. It scared the living daylights out of me. Upon closer looking and some poking via a stick, I figured it was a moth pupa, but I don’t know which moth caterpillar make it. Above it, there is a single strand of silk. It is about 7 cm (3.8 inches) long. Is it a bird decapitated by a spider or a pupa. If it’s a pupa, what pupa is it?

Dear TFO,
The quality of your images is quite poor, however we are able to distinguish the outline of the Chrysalis of a Swallowtail Butterfly in the genus
Papilio that was intact prior to your poking it with a stick.

We had to stop pulling weeds long enough to clean our hands and grab the camera.  Several Western Tiger Swallowtails were flying about the garden and nectaring from the plumbago on the neighbor’s hill.  It wasn’t so long ago that we lamented that we couldn’t get a decent image of the large Swallowtails sailing about as they never seemed to alight.

We even managed to get shots showing both ventral and dorsal surfaces.

Subject: What type of caterpillar is this?

Hey,
I live in Fairbanks, Alaska and this is the first time that I’ve seen one of these. We have a variety of butterflies and moths up here, but I’m not sure what species this particular one is. Any ideas?

Canadian Tiger Swallowtail Caterpillar

Dear Chris,
This is one of the Tiger Swallowtail Caterpillars, and there are many regional species.  We have trouble distinguishing one caterpillar from another, so we are researching ranges to help determine the species.  According to TurtlePuddle on the Canadian Tiger Swallowtail,
Papilio canadensis:  “These large and beautiful butterflies have been unusually abundant throughout the Anchorage area this summer (2002). … They are usually found in or near deciduous or mixed forests. They overwinter in the chrysalis. They range across much of Canada, Alaska, and several other northern states of the US. Adults nectar on a wide variety of flowers.”  According to BugGuide, the Canadian Tiger Swallowtail ranges in:  “northern US, Alaska, and every province and territory of Canada, north to the tundra” and “larvae feed on a wide variety of plants, including ash, cherry, poplar, and willow.”  BugGuide also has images of the caterpillar.

That was fast, thanks dan!

Hi
Can you identify this group of, what I guess are, moth larvae. These were in full view at the base of a tree at Chichen Itza, Yucatan, Mexico.
Many thanks

Good morning Bernard,
Though this is behavior that a person with some knowledge of insects might suspect would indicate that these are moth caterpillars, this is actually an aggregation of Ruby Spotted Swallowtail Caterpillars.  The Ruby Spotted Swallowtail is a lovely butterfly.  This social behavior is likely a survival strategy.

Thanks, Daniel, I am surprised!  I had assumed they were moth larvae.
Thanks again for your prompt reply
Best regards

Hi Tracie,
You are correct that this is one of the Tiger Swallowtail Caterpillars, which look very similar, and the orange color indicates that it is getting ready to pupate.  Several species are reported from Colorado according to BugGuide, including the Eastern Tiger Swallowtail and the Pale Swallowtail.
