Photo Details ŠNicky Davis Todd Stout collected Female 14 Jul 2014 just below boulders at top of Murdock Mountain, Utah. Since he was busy he gave me the female to have her oviposit and to rear the larvae. Females oviposited on native Potentilla diversifolia. Larvae reared on Fragaria vesca and Potentilla glandulosa. The glandulosa plants became spotted with some disease so I moved the larvae that were using it over to Fragaria vesca. They had no problem switching to the different plant. Female oviposited 115 eggs from 16 July to 3 August 2014. Twenty were given away. Of the remaining ninety five, sixty-six hatched for a hatch rate of sixty-nine per cent. Ova took about 8-10 days to emerge. First instar - 6 days Second Instar - 7 days Third Instar - 9 - 11 days Fourth Instar - 4-6 days Fifth Instar - 23-30 days Four larvae hatched morning of 24th July 2014 - 1.5-2 mm evening of 24 July 2014 On 27 July, 2014 these larva were 3 mm long Molted to second instar on 30 July 2014 Set to molt on 5 August - 5 mm long Molted to third instar 6 August 2014 Molted to fourth instar 17 August 2014 - 12 mm long Molted to fifth instar 19-20 August 2014 - 23 mm on 1 September First one pupated on 15 September 2014 - 16 mm long Hibernate as Pupae Pupa out of hibernation on 12 June 2015 and began eclosing 22 June 2015 Host Plant
