Photographer's Note

A large group of butterflies drinking from grass wet by a irrigatore.For a lover of butterflies, like me, this is was a very important and significant meeting.
The Mexican Yellow (Eurema mexicana, sometimes called the Wolf-Face Sulphur,is a North and South American butterfly in the family Pieridae. It occurs mainly in Mexico but occasionally is found in central and southwestern USA and rarely in Canada.
The upper side of the wings is pale yellow with a black fore wing submarginal border outlining a "dog" or "wolf-face" pattern. The hind wing has a small outer margin black border. The male has a bright yellow patch on the leading edge of the hind wing. The underside of the wings is pale yellow in summer individuals and pale yellow with reddish markings or all reddish-pink in winter individuals. The hind wing is sharply pointed.The wingspan measures 1¼ to 2¼ inches or 33-44 mm.
Similar species in the Mexican Yellow's range include Boisduval's Yellow (Eurema boisduvaliana) and the Salome Yellow (Eurema salome).
Boisduval's Yellow is smaller and brighter yellow, the male has a weaker "dog face" pattern, the female has reduced black on the upper side, and the hind wing is less sharply pointed.
The Salome Yellow is brighter yellow, has more limited black on the upper side, and the underside of the hind wing has a round reddish spot near the trailing edge.
The Mexican Yellow lives in a variety of open habitats such as woodland edges, open woodlands, and desert grasslands.
