LIFE
HISTORY:
Two females oviposited over several days on sedge, the screen on
the
side of the cage and the tricot material that covered the top of
the
cage. One hundred ten ova hatched. Forty ova were given to Todd
Stout
who located the females
Ova: 12 days
Larvae: Variable since about half the larvae
hibernated at
second instar even though they were reared at about 78 degrees and with
24 x 7 lights. Three stopped eating, walked off the plant, became
shorter and wider then formed pupae. Twenty-one sixth instars have not
pupated nor hibernated. They are still feeding but at a slow
rate.
Nine larvae that had stopped feeding at second instar began feeding
again before they were put into hibernation temperatures and are still
feeding as of the middle of October. They are now last instars.
Pupae: 7 - 9 days
Adult: Unknown but I had the adult females for a couple of
weeks and they continued to oviposit until the last day.
Broods: Biennial per "Butterflies of North America" - James
A. Scott. 1986
Hibernation: Overwinter as first to third instar the first
year
and as fourth to sixth instar the second year per "Buterflies of North
America"- James A. Scott. 1986
