Rare
Under 5% of wildlife watchers report a Physocephala burgessi sighting in Seattle on a given day, based on 49 verified sightings from GBIF citizen-science data. It is the 112th most-seen of the 428 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.
May to July
In those months about 10% of wildlife watchers report a Physocephala burgessi in Seattle on a given day, against under 5% in August to April, the lowest months. Those are among Seattle's driest months, with about 45 mm of rain a month against 190 mm in November.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Physocephala burgessi sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 cities where we can rate Physocephala burgessi sightings, Seattle has the highest daily chance: under 5%. Next come Portland (United States, under 5%) and San Francisco (United States, under 5%).
Same order: Diptera
The closest relatives of the Physocephala burgessi that you can see in Seattle (order Diptera, Flies) are Yellow-Haired Sun Fly (about 10%), Eurasian Drone Fly (about 10%) and Narcissus Bulb Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Physocephala burgessi is recorded against all the insects logged in Seattle (49 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.
