Description

Specimens from south Brazil, Uruguay and Argentina differ so little that they cannot be separated. This form is in the male dark orange yellow, specimens with violet reflections are not rare; the black-brown distal margin is not sharply defined proximally. The under surface with the exception of the reddish middle of the forewing is vivid yellow with the usual Colias marking. The ground colour of the upper surface in the females is very variable: orange yellow, yellow, yellowish or white with grey dusting; greenish-grey specimens also occur.
