The female is available in both orange and white form, where the black submarginal boat is dreddere with yellow spots.

Rear wing underside is green with diffuse gray to black scales.

Wingspan: 27 - 34 mm.

Habitats: This species breeds on dry puna grasslands and lightly grazed pastures at elevations between 3500-4600 metres, in areas bathed in the warm sunshine above the cloud line for most of the year.

Behaviour: Migrating adults fly rapidly across the Andean grasslands, stopping momentarily to nectar at any available flowers, and often patrolling back and forth along ridges. Often seen flying over cultivated fields of clover and alfalfa.

Flight: For several generations in all months of the year.

Foodplants: The larval feed on plants including Leguminous herbs such as Lotus, Vicia, Trifolium and Astragalus.

Distribution: Andean Altiplano plateau from Chile, Bolivia, Peru to Ecuador.

The female is available in both orange and white form, where the black submarginal boat is dreddere with yellow spots.

Rear wing underside is yellow with red spot.

Wingspan: 38 - 45 mm.

Habitats: Grasslands and lightly grazed pastures at elevations of between 2500-4000m. These high altitude habitats are above the cloud line and bathed in warm sunshine throughout most of the year. Daytime temperatures can be as high as 25°C, but can fall to below freezing point at night.

Behaviour: The adults are extremely mobile and usually seen as wandering singletons, but they can be found in colonies of several dozen individuals at their breeding sites.

Males sometimes settle as damp mud to imbibe mineralised moisture. They patrol back and forth across their grassy habitats in search of potential mates, interrupting their search periodically to nectar at tall "ox-eye" daises, or to rest on bare ground.

Flight: For several generations in all months of the year.

Foodplants: The natural foodplant is likely to be a related leguminous plant, e.g. some North American Colias species feed on Lotus, Vicia, Trifolium and Astragalus species.

In Argentina, where C. Lesbia can act as pests in Alfalfa, Medicago sativa fields trying to biological control with Bacillus thuringiensis endotoxin.

Distribution: Andean Altiplano plateau from Argentina, Chile, Bolivia, Peru, Ecuador to Columbia.
