Rare
Under 5% of wildlife watchers report a Physocephala burgessi sighting in Vancouver on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 374th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Physocephala burgessi in Vancouver 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 Physocephala burgessi sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Physocephala burgessi sightings, Vancouver ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Seattle (United States, under 5%), 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 Vancouver (order Diptera, Flies) are Black-Margined Flower Fly (about 10%), Common Drone Fly (about 10%) and Common European Greenbottle 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 Vancouver (7 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.
