With luck
About 10% of wildlife watchers report an Umber Skipper sighting in Sacramento on a given day, based on 53 verified sightings from GBIF citizen-science data. It is the 95th most-seen of the 386 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April–June and August–September
In those months about 10% of wildlife watchers report an Umber Skipper in Sacramento on a given day, against under 5% in July and October–March, the lowest months. Those are among Sacramento's driest months, with about 15 mm of rain a month against 120 mm in December.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Umber 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.
4th of 4
Of the 4 cities where we can rate Umber Skipper sightings, Sacramento ranks 4th at about 10%. The best odds are in San Francisco (United States, about 20%), Los Angeles (United States, about 10%) and San Diego (United States, about 10%).
Same family: Hesperiidae
The closest relatives of the Umber Skipper that you can see in Sacramento (family Hesperiidae, Skippers) are Fiery Skipper (about 20%), Mournful Duskywing (about 20%) and Common Checkered-Skipper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Umber Skipper is recorded against all the insects logged in Sacramento (53 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.
