| PHOTO DETAILS - ©Nicky Davis LOCATION: On 2 July 2010 two females were located by Todd Stout reared by Nicky Davis at Christmas Meadows Road; East side of Utah Highway 150, .4 miles ESE Stillwater Campground, Summit County, Utah ELEVATION: 8600 Feet PHOTOS: The pupa was placed by the twig so the adult could use it to crawl up to inflate and dry its wings. This one was not satisfied with the arrangement and the pupal shell was stuck on her for a few seconds. With a little guidance and help she made it onto the twig and inflated her wings. I rotated the photos to allow for a larger photo. The twig was actually vertical. LIFE HISTORY: Two females oviposited over several days on sedge, the screen on the side of the cage and the tricot material that covered the top of the cage. One hundred ten ova hatched. Forty ova were given to Todd Stout who located the females Ova: 12 days Larvae: Variable since about half the larvae hibernated at second instar even though they were reared at about 78 degrees and with 24 x 7 lights. Three stopped eating, walked off the plant, became shorter and wider then formed pupae. Twenty-one sixth instars have not pupated nor hibernated. They are still feeding but at a slow rate. Nine larvae that had stopped feeding at second instar began feeding again before they were put into hibernation temperatures and are still feeding as of the middle of October. They are now last instars. Pupae: 7 - 9 days Adult: Unknown but I had the adult females for a couple of weeks and they continued to oviposit until the last day. Broods: Biennial per "Butterflies of North America" - James A. Scott. 1986 Hibernation: Overwinter as first to third instar the first year and as fourth to sixth instar the second year per "Buterflies of North America"- James A. Scott. 1986 Back to Top |
