Identification

often exhibit orange or coloration, with some showing distinctive orange on . of Anthocharis species can be identified to species group by fifth and pupal cone curvature. (mitochondrial COI) reliably separates most species groups, though some recently diverged species pairs may show overlapping barcode variation.

Distribution

Widespread across the Northern Hemisphere. North representatives include: the lanceolata and sara groups in western North America; the cethura group in southwestern North America; and the midea group ranging from northeastern USA south to Hidalgo, Mexico.

Life Cycle

Fifth and pupal cone curvature serve as diagnostic morphological characters for identification in Anthocharis.

Speciation patterns in North American Anthocharis

barcode studies reveal four groups with distinct evolutionary : (1) lanceolata group with deepest divergence (~2.7% between species); (2) sara group with three well-defined species and notable intraspecific divergence in A. thoosa; (3) cethura group with minimal divergence, treated as single variable species; (4) midea group showing north-south barcode gradient suggesting recent vicariant speciation with incomplete genetic separation
