With luck
About 10% of wildlife watchers report a Rhagio tringaria sighting in Vancouver on a given day, based on 68 verified sightings from GBIF citizen-science data. It is the 95th 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 30%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Rhagio tringaria in Vancouver on a given day, against under 5% in September to May, the lowest months. Those are among Vancouver's driest months, with about 35 mm of rain a month against 210 mm in November.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Rhagio tringaria sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 17 cities where we can rate Rhagio tringaria sightings, Vancouver ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Helsinki (Finland, about 10%) and Rotterdam [The Hague] (Netherlands, about 10%).
Same order: Diptera
The closest relatives of the Rhagio tringaria 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 Rhagio tringaria is recorded against all the insects logged in Vancouver (68 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.
