Members of the Utah Butterfly Club went on an outing to Welcome Springs, Washington County, Utah on 18 March 2017 where female Coloro butterflies were located.  The following week, Tony Jones arranged the female coloros on host plant to acquire ova.  Todd Stout and Sheryl Stout removed the ova from the host plant and placed in containers for the members interested in rearing the butterflies.  Larvae began emerging from ova March 29, 2017.

Adults were then mated black to black? .  Photo of one butterfly that emerged
