Female on lid of screen box used to house females while they oviposited.
These butterflies would not lay in the box with a pansy inside.
Female preferred ovipositing inside a brown paper lunch bag
with a few dead pansy stems in the bottom.
A female laid this egg on a dead pansy stem inside the paper bag
Top view of the egg
Females laid this egg and many more on the inside of a paper bag.
This was definitely their preferred surface.

DETAILS - ©Nicky Davis LOCATION: Murdock Mountain, Uinta Mountains, Summit County, Utah on 1 August 2009 GPS North 40.43.44.54, West 110.54.06.25 West Elevation 10, 298 feet. When eggs hatched, I tried a limited number of larvae in lidded twin cups using pansy leaves with a wet piece of paper towel in the bottom of the cups for hydration. They were kept under a lamp 24 x 7. A couple of them nibbled at the leaves but then stopped and refused the leaves. Later I tried two with the same set-up but using a Diamondleaf Willow, Salix planifolia and they started to feed and it. Since it was too late in the year to continue feeding them this plant, I put these two first instars in the fridge with the others. I over-wintered them at about 30 to 35 degrees in a chiffon hammock in a solo cup with needle holes in then placed in a cross-ventilated plastic sandwich container holding a solo cup full of water to hydrate. On 15 June 2010, when Salix planifolia was available, the larvae were removed from hibernation and placed on the plant using the twin cup method. They began to feed in three to four days. After eighteen days #9 formed a "J" and was set to pupate. The pupa formed on 11 July 2010 and the adult emerged 16 July 2010. The rest of the larvae fed intermittently on the plant for the remainder of the summer but never formed a pupa. They were finally set back into hibernation. PHOTOS: See notations above each photo LIFE HISTORY: Ovum: 6 TO 9 DAYS Larva: Over-winter as first instar and then these fed for about 18 days. Pupa: Five days Adult: Unknown Broods: One brood every other year per "Butterflies of North America" James A. Scott Hibernation: Overwinters as first instar and as last instar per "Butterflies of North America" James A. Scott NAME CHANGES - Andy Warren - December 2010 In 1998, all North American Boloria "titania" became ssp. of Boloria "chariclea". Recent DNA evidence (in press at the moment) corroborates the idea that we Host Plants listed in The Butterflies of North American by James A. Scott Salix sp. (Alta), reticulata (S. Alaska & Churchill, Man.)S. artica, (Churchill); Polygonum (Europe), P. bistortoides (Wash.), viviparium, (N. Amer.); viola pallens (ont), V. adunca (Wyom); Dryas integrifolia (Greenland), Assoc. with Salix herbaceanin S.E. Can. & with Salix reticulata ssp. nivalis in Color, young larvae eat viola in lab in Color. per J. Scott). Oviposit observed on vacinium Augustifolium (Ericaceae, Ont.) V. sp. (N. Que), & V. scoparium (Color.). All possible hosts and on Trollius laxus (ranunculaceae, Colo.), a doubtful host. As mentioned above these larvae used Diamondleaf Willow, Salix planifolia Back to Top |
