FOODPLANT OF HYPAUROTIS CHRYSALUS (LYOENIDjE)
IN COLORADO
Since no definite record of the foodplant of Hypaurotis chrysalus (Edwards) seems to have been published, I am recording some casual observations made on this point several years in western Colorado. I watched individual females lay single eggs in crevices in bark of the common scrub oak, Quercus gambelii Nutt., at the western approach to Rabbit Ears Pass in Routt County, at about 10 miles west of Glenwood Springs in Garfield County, and at about 8 miles east of Somerset in Gunnison County. On 10 August 1954, I took several wild females from the Garfield County locality and confined them with twigs of the oak, in the manner we often use for Theclines. One egg was laid on 12 August and one the next day, both in rough paches of bark. The females then died of overheating in the sun. The eggs were refrigerated that winter but did not hatch when brought out in spring.
