Females oviposited on
Alpine Mountain Sorrel, Oxyria digyna
They hatched 28 July 2009
LARVAE
Larvae were fed Rumex
crispus
cuttings in 1/2 ounce solo cups which were changed morning and
evening to keep them clean and healthy. They were also kept at about 76
degrees and 24x7 light. Number two grew at an astonishing rate and was
pre-pupa on the 9th of August, only 12 days from hatching. Pupa
formed on the 11th of August. #2 butterfly eclosed after only 6
days as a pupa. The other larvae were a little slower with the
last one forming a pupa on the 16th of August. Most of these
eclosed after 7 days.
Photos are of the larvae
from 2nd instar to pre-pupa.
