Using his mercury vapor light on 10 July 2015, John Richards caught a female One-eyed Sphinx Moth, Smerinthis cerisyi 1/2 mile east of the mouth of South Willow  Canyon, Tooele County, Utah. I received first Instar larvae from John Richards and his friend Curt on 22 July 2015
First instars were first placed on willow which was rejected.  They were then placed back on Aspen leaves and they began feeding.

After walking off the plant they were each placed in a plastic, lidded  container filled with sand and lizard litter to pupate. At the bottom of the container, they each silked a loose nest using some of the lizard litter.
After 3-4 days they pupated.
