Photo Details - İNicky Davis
On August 26, 2006,  ova and larvae located  on private property in Salt Lake County with permission granted from property owner.  All these photos are not of the same individual.  The larvae that developed from the two ovum collected  are much larger than the two larvae collected  as young instars.
