Dainty Sulphur

The dainty sulphur is the smallest sulphur in North America. Compared to other sulphurs, the forewings of this species are rather elongated. Dainty sulphurs typically fly just inches above the ground. The upperside is yellow with black forewing tips. Black upperside markings are more extensive in females. On the undersides of the forewing, the discal cell (at the basal core of the wing) is orange or a deep yellow, and there are two black spots positioned rather near the outside edge. The underside of the hindwing is pale yellow in the summer, but it is dark olive green at the end of the flight season.
