Female
located July 16, 2007.
Guardsman Pass, Salt Lake County,
Utah. Ova laid July 17, 2007. After a few days these were
put into the refrigerator to hibernate. They were kept fresh by
keeping them taped to the side of a clay pot with a sauce cup full of
water in the bottom. The clay pot was then placed in a plastic bowl
with a lid on but opened at one side for circulation. They were
checked every other week in attempt to keep them hydrated but not so
damp that they would mold.
However,
this method did not
work and none of the ova eclosed.
In the summer of 2008, I
located another female and again over
wintered the ova. This time I put them into a chiffon hammock
hanging inside a solo cup pierced with a needle on every surface.
The solo cup was then put inside another plastic container that had
other hibernating insects in it. It had two holes in
it to provide some ventilation and two open solo cups full of water for
hydration. The temperature was gradually brought down to
freezing. This method worked and most of the ova hatched.
Eggs were removed from hibernation 6 May 2009 and when they hatched, 8
May 2009, they were placed on Eriogonum heracleoides. They did well on this plant and went on
through to
pupa, then butterflies.
