Rare
Under 5% of wildlife watchers report a Woodland Skipper sighting in Denver on a given day, based on 40 verified sightings from GBIF citizen-science data. It is the 166th most-seen of the 461 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Woodland Skipper in Denver on a given day, against under 5% in September to June, the lowest months. Those are among Denver's wettest months, with about 55 mm of rain a month against 15 mm in January.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Woodland Skipper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
9th of 10
Of the 10 cities where we can rate Woodland Skipper sightings, Denver ranks 9th at under 5%. The best odds are in Seattle (United States, about 20%), Portland (United States, about 10%) and Vancouver (Canada, about 10%).
Same family: Hesperiidae
The closest relatives of the Woodland Skipper that you can see in Denver (family Hesperiidae, Skippers) are Common Checkered-Skipper (about 20%), Taxiles Skipper (about 10%) and Peck's Skipper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Woodland Skipper is recorded against all the insects logged in Denver (40 verified sightings), 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.
