Under 5% of wildlife watchers report a Swarthy Skipper sighting in Washington on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1649th most-seen of the 1807 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Swarthy Skipper in Washington on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Swarthy Skipper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Washington, in our data
Washington is the only city on Wallace's Line with enough records to rate Swarthy Skipper sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Hesperiidae

GBIF citizen-science records
It is estimated from how often the Swarthy Skipper is recorded against all the insects logged in Washington (5 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.
