Polites sabuleti, the sandhill skipper or saltgrass skipper, is a butterfly in the family Hesperiidae. It is found from southern British Columbia and eastern Washington, south through California and northern Arizona to Baja California and east to south-eastern Wyoming, central Colorado, and north-eastern New Mexico. It is an introduced species in Hawaii.
The wingspan is 22–32 mm. There is one generation with adults on wing from June to August at high elevations. There are several generations from March to October in the southern part of its range and at low elevations. The larvae feed on various grasses, including Cynodon dactylon, Poa pratensis, Distichlis spicata var. stricta, Eragrostis trichodes, Agrostis scabra, Festuca idahoensis, and Festuca brachyphylla. Adults feed on flower nectar. Wikipedia →

Possible
About 20% of wildlife watchers report a Sandhill Skipper sighting in Yosemite National Park on a given day, based on 111 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 227 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Sandhill Skipper in Yosemite National Park on a given day, against under 5% in September to May, the lowest months. That is one of Yosemite National Park's driest months, with about 25 mm of rain against 220 mm in January.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Sandhill Skipper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 parks where we can rate Sandhill Skipper sightings, Yosemite National Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Kluane National Park (Canada, about 20%).
GBIF citizen-science records
It is estimated from how often the Sandhill Skipper is recorded against all the insects logged in Yosemite National Park (111 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
