Rare
Under 5% of wildlife watchers report a Diamond Spottail sighting in Sacramento on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 184th most-seen of the 386 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.
April and June–July
In those months about 10% of wildlife watchers report a Diamond Spottail in Sacramento on a given day, against under 5% in May and August–March, the lowest months. Those are among Sacramento's driest months, with about 20 mm of rain a month against 120 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.
Yes
Of the 8 cities where we can rate Diamond Spottail sightings, Sacramento has the highest daily chance: under 5%. Next come San Francisco (United States, under 5%) and Vancouver (Canada, under 5%).
Same family: Syrphidae
The closest relatives of the Diamond Spottail that you can see in Sacramento (family Syrphidae, Hover Flies) are Western Aphideater (about 20%), Margined Calligrapher (about 20%) and Oblique Streaktail (about 20%), 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 Sacramento (15 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.
