Rare
Under 5% of wildlife watchers report an Okanagana napa sighting in Sacramento on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 154th most-seen of the 386 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.
June and July
In those months about 10% of wildlife watchers report an Okanagana napa in Sacramento on a given day, against under 5% in August to May, the lowest months. Those are among Sacramento's driest months, with almost no rain against 120 mm in December.
Only Sacramento, in our data
Sacramento is the only city on Wallace's Line with enough records to rate Okanagana napa sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Hemiptera
The closest relatives of the Okanagana napa that you can see in Sacramento (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Leptoglossus zonatus (about 20%), Western Boxelder Bug (about 20%) and Leafhopper Assassin Bug (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Okanagana napa is recorded against all the insects logged in Sacramento (23 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.
