©Nicky Davis Female located July 16, 2007. Guardman's 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.
