Davis Female located on a wild lathyrus plant in Butterfield Canyon. She laid 17 eggs at the base of the flowers or the tiny flower stem of this same plant. The eggs took four days to hatch. larvae were placed on the flowers of various legumes such as Astragalus cicer, unknown milk vetch, Lathyrus latifolius and Hedysarum boreale to see which plant the larva preferred. They immediately went inside the blossoms. This larva fed on Astragalus cicer Pupa Pupa #3 just formed June 28, 2007 Larva 1., 2.
