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
