Colias dimera flies up in the Andes from Venezuela to Peru (Verhulst 2000). it can be common at elevations of 2500/3500 meters and more.
in the Park we saw it near the Tungurahua volcano, along the Riobamba/Ambato road and in the upper valley of rio Paute.
there are two forms for the female: one very similar to the male, the other one a yellowish/greenish white.
