Caring for Live Female Butterflies: Nectaring techniques (Females nectar as soon as feet sense moisture)
How to Find Eggs: Look on Flower Stems. (A. lanceolata lanceolata ova are much larger than Euchloe or Anthocharis sara ova.)
How to Hatch Eggs: Separate eggs individually.
How to Find Caterpillars in the Field: Look for Caterpillar Strip Patterns. Last instar larvae make a conspicuous strip pattern on the flowers of their mustard host plant. Look for younger larvae on siliques. Eggs are much easier to find than larvae as many larvae get consumed by predators.
How to Find Pupae in the Field:
Larva to Pupa: Larva Changes Color
Number of Broods per Year: 1
Overwintering Stage: Pupa.
Avoiding Diapause Techniques:
Disease Prevention: Change out host plant and remove frass every three to five days.
Emergence: Emergence Container
Field Notes: Unlike Anthocharis sara and Anthocharis cethura complexes, larvae refuse Descurainia pinnata.
