Photo Life History: Anthocharis sara
Habitat: Mountain Canyons
Caring for Live Female Butterflies: Feed females regularly; Do NOT place live females in glassine envelopes for ANY period of time. They are too fragile.
How to Find Caterpillars in the Field: It is abundantly easier to find eggs and/or to get eggs out of live females. But, to find late instar larvae, (many will have been taken out by predation) look for Caterpillar Strip Patterns.
Overwintering Stage: Pupa.
Larva to Pupa: Larva Changes Color (goes from dark green to much darker green)
Number of Broods per Year: 1-2 depending upon location.
Avoiding Diapause Techniques: Not effective for univoltine populations; however, if you provide larvae of bivoltine populations Healthy Host Plant, or expose late instar larvae and/or pupae to rain water, that seems to encourage same year emergence of bivoltine populations.
Disease Prevention: Change out host plant and remove frass every three to four days.
Emergence: Emergence Container
Field Notes: Anthocharis sara sempervirens pupae will sometimes emerge same year. Due to field research (in press), subspecies sara, sempervirens, gunderi, and pseudothoosa are applied to species 'sara'.
