Rare
Under 5% of wildlife watchers report a Diamond Spottail sighting in San Francisco on a given day, based on 103 verified sightings from GBIF citizen-science data. It is the 152nd most-seen of the 737 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
In that month about 10% of wildlife watchers report a Diamond Spottail in San Francisco on a given day, against under 5% in July to May, the lowest months. That is one of San Francisco's driest months, with almost no rain against 110 mm in December.
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, San Francisco ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Sacramento (United States, under 5%).
Same family: Syrphidae
The closest relatives of the Diamond Spottail that you can see in San Francisco (family Syrphidae, Hover Flies) are Oblique Streaktail (about 10%), Eurasian Drone Fly (about 10%) and Thick-Legged Hover 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 San Francisco (103 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.
