Eurema brigitta, know as the Broad-bordered Grass Yellow, Small Grass Yellow, or No Brand Grass Yellow is a small (adult wingspan 28-45 mm), bright yellow butterfly in family Pieridae.There are about 55 species in genus Eurema; E. brigitta can be distinguished from its similar congenitors by its lack of black spots on the unside of the forewing.One of the 15 most common butterflies in Africa, Arabia and Southeast Asia, the Small Grass Yellow is widespread in almost all countries in both continents, including Madagascar and other islands.It also occurs in Papua New Guinea and Australia. This habitat generalist lives mainly in open grasslands, clearings and disturbed areas, up to altitudes of 2400 m. Adults eat flower nectar; males also mud puddle on sand or dung, often in large migratory congregations.The larvae, which grow to about 3 cm long have a darker green back and lighter lateral stripes.Larvae feed on hostplants in the family Fabaceae (Leguminaceae): especially Chamaecrista mimosoides,Neptunia dimorphantha (in Australia), species in the genera Senna,Sesbania,Albizia,Acacia, andTephrosia and Hypericum aethiopicum (family Hypericaceae).For a nice photo description of the life history of this species, see http://www.butterflycircle.blogspot.com/2009/10/life-history-of-no-brand-grass-yellow.html

Eurema brigitta, the small grass yellow[4][5] or broad-bordered grass yellow, is a small butterfly of the family Pieridae, that is, the yellows and whites. It is found in India, other parts of Asia, Australia and Africa.[4][5][3][2]
Wet-season form: Male. Upper-side somewhat paler yellow. Fore-wing with the outer marginal black band; the apical edge of costa and the cilia rosy-red. Hind-wing with the black outer band somewhat narrower, macular, the decreasing portions each with a more prolonged inner-tooth, and the yellow ground-colour between each extending to the outer edge. Underside pale yellow, the fore-wing also having a very slightly defined sub-apical inwardly-oblique squamous streak. Fore-wing with the entire costal edge and outer marginal cilia, and also the outer marginal cilia of the hind-wing, rosy-red. Female. Upper-side. Apical edge between the subcostals of fore-wing, and cilia of both wings paler rosy-red. Underside with the markings on hind-wing slightly visible. Fore-wing above with the black outer band broken beneath the lower median veinlet. Hind-wing with the outer band similar to male, its portions slightly broader. Underside similar to male, the markings being slightly more defined.
Intermediate form: Male. Upper-side. Fore-wing with the outer band slightly narrower than in wet form; cilia paler red. Hind-wing with the marginal macular band narrower, and composed of smaller portions. Underside similar to wet form. Female. Upperside. Fore-wing with the outer band less broken at its posterior end than in wet form. Hind-wing with the marginal macular band less distinct and narrower. Underside similar to the male.
Dry-season form: Both sexes much smaller than in intermediate form. Cilia paler. Male. Fore-wing above with the inner-edge of the marginal band less sinuated than in intermediate form, its posterior end indistinctly broken. Hind-wing with the lower portions of the macular band somewhat larger and less dentate. Underside. Both wings with less defined markings than in intermediate form. Female. Upper-side. Fore-wing with the band slightly broken at posterior end. Hind-wing with the lower portions of band somewhat wider. Underside with the markings indistinct.
The wingspan is 30–35 mm. Adults are on the wing year-round.[6]
The larvae feed on Hypericum aethiopicum and Chamaecrista mimosoides.[6]
