Nicky
Davis & Todd Stout collected two larvae 19 July, 2011 in
Lambs Canyon, Salt Lake County, Utah
These
larvae make a nest by silking onto the edges of a leaf and
pulling the edges together into an upward or "bowl" position.
However, when ready to pupate, a larva silks a leaf together upside
down or in an "umbrella" position.
The
pupa took 8 days to develop and the butterfly to emerge.

2.5 miles East of Mount Aire, Lambs Canyon which is on the east side of
the Wasatch mountain, Salt Lake County, Utah - 7200 feet.
After
a few days the pupa showed discoloration and was found to have
been parasitized by a fly as a young instar prior to Todd collecting it.
