Jack Harry located 2 female Pine Elfins on June 9, 2009
LOCATION: Black Rock Canyon, Tooele County, Utah
GPS 40.01.5706 N, 112.11.5613 W, Elevation 6497 feet
Females laid 4 eggs 9 June, 10 eggs 12 June, 2009. They stopped laying after 9 June so on 12 June we cut fresh
Pinyon Pine boughs, put a small sprig in a bouquet in a medicine bottle
and used a plastic container with some chiffon under the plastic
lid. I used a small lid with a little piece of honey-soaked
sponge in it for the females to nectar on as needed. I set
the container holding the females in the sun on grass in the
afternoon for 1/2 hour, then in the house in the dark 1/2 hour,
back out in the sun again and so on. I also spritzed the pine
bough just a bit for added hydration. The females liked this
arrangement and laid 10 eggs. They only laid on the
unopened pine needle tips that were cut the same morning.
I wanted to have new, fresh pine boughs when the larvae hatched
so I popped the eggs off the pine to store them which resulted in half
the eggs not hatching. At least I believe that's why they all
After 45 days the pupae were put in a chiffon hammock and
suspended in a container with some water in the bottom to keep
them hydrated. They were then put in the fridge at about 40
degrees. On October 30, 2009 they will be transferred to a
small fridge with the temperature at about 30 to 35 degrees F.
The goal is to keep them hydrated and at the temperatures they
encounter in the wild under snow.
