member of the cosmopolitan insect family Pieridae (order Lepidoptera) that also includes the white and the orange-tip butterflies. Adults have a wingspan of 35 to 60 mm (1.5 to 2.5 inches). Sexual and seasonal dimorphism in pattern and colour occur in many species. The pupae are attached to a twig by a posterior spine and a girdle of silk. The sulfurs are generally bright yellow or orange. Some species have two colour patterns; e.g., Colias eurytheme is usually orange with black wing margins, but some females are white with black margins. The larvae feed on clover and may seriously damage crops.
