The Orange Sulphur, also called the Alfalfa Butterfly, is one of North America's most abundant butterflies, with males displaying vivid orange wings bordered in black. Females occur in both yellow and white forms, and adults often congregate in large numbers at moist soil or wet sand. Its success is partly due to the widespread cultivation of alfalfa, the primary larval host.
