Rare
Under 5% of wildlife watchers report a Diamond Spottail sighting in Vancouver on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 187th 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.
June and July
In those months about 10% of wildlife watchers report a Diamond Spottail in Vancouver on a given day, against under 5% in August 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 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Diamond Spottail 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 8 cities where we can rate Diamond Spottail sightings, Vancouver ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Sacramento (United States, under 5%) and San Francisco (United States, under 5%).
Same family: Syrphidae
The closest relatives of the Diamond Spottail that you can see in Vancouver (family Syrphidae, Hover Flies) are Black-Margined Flower Fly (about 10%), Common Drone Fly (about 10%) and Eurasian Drone Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Diamond Spottail is recorded against all the insects logged in Vancouver (27 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.
