Caring for Live Female Butterflies:  Nectaring techniques (Females nectar as soon as feet sense moisture)

Methods of Female Oviposition:  Open Screen Cages; Portable Cages.  (There is no need to wait to set up females for oviposition.  They should lay eggs soon after capture.)

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: 

Caterpillar setups:  Open terrariums; Open Bucket

Larva to Pupa:  Larva Changes Color 

Number of Broods per Year:  1

Overwintering Stage:  Pupa. 

Overwintering Strategies: Your Own Backyard; Refrigerator

Post-Hibernation Strategies: Expose Pupae to warmer temperatures; Long-Day Photoperiod; High Humidity

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.
