The Dainty Sulphur is the smallest sulphur butterfly in North America, barely over an inch in wingspan, with pale yellow wings and distinctive dark markings at the wing tips and along the inner hindwing margin. Despite its tiny size it is a strong migrant, expanding northward in summer. Adults fly close to the ground and are easily overlooked among weeds.
