and other Details - ©Nicky Davis Two females located by Todd Stout on Murdock Mountain. On July 27, 2008, Jack Harry, Les Davis and I located two females past mm 27 along the Mirror Lake Highway, Duchesne County, Utah. All females were returned to the same area after we obtained these eggs. N. 40.40.881, W. 110.55.165 Elevation 10,349 feet Ova These females oviposited 160 ova on an unknown Vaccinium within a couple of days. They hatched after four days. Larva We put the larvae on Salix exigua (Brush Willow) which they refused to feed on, and all but 50 died. We moved the surviving 50 larvae to Diamondleaf Willow, Salix planifolia which was growing at the same location in which the females were flying. The larvae fed on that plant just fine. I kept them under light 24x7, nevertheless they all hibernated except one. Pupa A pupa formed 1 May 2009 and male butterfly hatched after eight days. Male #2 emerging from pupa 11:10 A.M. on 9 May 2009 Host The females oviposited on an unknown vaccinium and the larvae fed on D. Willow - Salix planifolia. After hibernation, they fed on Salix exigua. For photos of the host plant used, click on Diamondleaf Willow, Salix planifolia Salix exigua Back to Top |
