| Status: Uncommon to common stray. |
| Flight Period(s): This species flies throughout the year in southern portions of its home range. In Nebraska where it has been found from 11 May – 24 October it is most likely to be encountered in late summer. |
| Range: The Cloudless Sulphur inhabits both Americas, ranging south as far as Patagonia. In North America it is a permanent resident as far north as the Gulf Coast and along the Atlantic seaboard up to North Carolina. From there it strays northward to the Canadian border, being absent only in the Pacific Northwest. It has been found throughout Nebraska, but becomes common only in the south and southeast. |
