I have found a Canadian Tiger Swallowtail in Polson Montana, I am 9 years old and would like to winter the pupae. It is dark Brown/red now, if you can help me with information that would be great. I have taken pictures and hope to document the winter stage to release.
In answer to Gabriel, if the pupa is dark brown or red now, it might have some sort of disease. It should be light gray brown or even greenish. But if you are referring to the late stage larva, then that is okay. You can see a photo of a brown larva at the Royal Alberta Museum website at: http://www.royalalbertamuseum.ca/natural/insects/bugsfaq/swallow.htm
This species overwinters in the pupal stage and can be kept in a container (so the mice don''t get it) in your yard or your fridge during the winter months.
We found 1 yesterday in Medicine Hat,Alberta.It is about 2 inchs long.Are they supposed to give off a bad odor when disturbed?
Felix Sperling (2010-09-25)
Yes, if the bad odor is a bit like vinegar, then that is one of the ways in which they defend themselves. It comes out when they evert an organ behind the head called an osmeterium.

Just found one today eat wood in the Children's Garden at the Missouri Botanical Gardens. At first I thought my son found a pretend larvae attached to a chopped piece of wood. However, when my son touched it reared up and stuck out a tongue looking body part. So we took the picture so we could identify it tonight. We did!

Pterourus canadensis Rothchild & Jordan, 1906
(a) Voltinism. My field observation and rearings of several dozens of specimens of this species over several years, indicate that Canadian Tiger Swallowtail in Alberta could be, in some years, partially bivoltine.
(b) Life cycle. The winter is passed in the pupal stage. In Edmonton and surrounding areas, the spring emergence coincides with the onset of flowering of Lilacs (early part of May). The males seem to emerge before females. In the parking lot at the Devonian Gardens, I observed several times nectaring males on several Lilacs shrubs planted there. Displaying typical papilionid nectaring behaviour, the butterflies hover around the flowers, nectaring in flight, without alighting on the inflorescence. Slightly larger, paler females seem to emerge later. While males sometime congregate in large numbers in puddling clubs, females (seen so far) were typically solitary. The green, spherical eggs, were deposited singly on the upper surface of leaves of willows (Salix spp.). The larvae will readily accept Trembling Aspen (Populus tremuloides) as the food plant. I grew two aspen saplings, planted in my back yard for this purpose. The green, Pterourus larva with paired ocular marking on the 2nd thoracic segment looks strikingly different from the striped Papilio larval type. Just before pupating, the coloration of the mature green larva turns to darker, brownish-purple. The pupa is attached to the substrate by the caudal silken pad and by a silken dorsal girdle.
