This big beautiful Pierid Butterfly was fluttering about in the grass, obviously very agitated. It let me take pictures but stayed down in the grass, which I thought was odd. When I saw the pictures, there was a red ant clasped onto one of her legs. She must have been asking me for help and I was too unobservant to notice, so I feel badly for leaving :( Family Pieridae.
Heavy vegetation, km 11.5, Highway between Chiapa de Corzo and San Cristobal de Las Casas, 865 meters.
See the reference for pictures of the upper side of the butterfly as well as the larva.
