The sexes are alike. The shape of the outer margin of its hindwing is truncated, being more prominent in dry season individuals. It has a broad, regular black outer margin on the upper surface of its forewing. The outer margin of its hindwing is also broad, but not as broad as that on the forewing. Its underside is dusted with scattered black scales and is sporadically interspersed with a few small black spots. The dustings on the hindwing sometimes form distal bands. Its cell end spots are never large enough to form a hollow centre. It does not have any markings on the base of its forewing cell.
The Small Grass Yellow prefers to fly quite slowly near the ground. It frequently settles among grass blades and is disturbed by even a slight movement of the grasses. It does not open its wings when settling and rarely settles on mud patches.
Habitats and Distribution
