Hesperia uncas, the Uncas skipper or white-vein skipper, is a butterfly of the family Hesperiidae. It is found from US Midwest to southern portions of the three Canadian Prairie provinces, north as far as Edmonton, Alberta.[1]

The wingspan is 32–42 mm. There are two generations per year with adults on wing from May to June and again from August to September, in Canada from mid-June to late July.[1] It is found in sandy areas, open woodlands, and sagebrush.[2]

The larvae feed on Deschampsia elongata, Stipa, Bromus rubens, and Poa pratensis. Adults feed on flower nectar from various flowers, including rabbitbrush, needlegrass (Stipa nevadensis), and blue grama (Bouteloua gracilis).[3]
