Rare
Under 5% of wildlife watchers report a Eurasian Baskettail sighting in Yekaterinburg on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 155 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.
May and June
In those months about 10% of wildlife watchers report a Eurasian Baskettail in Yekaterinburg on a given day, against under 5% in July to April, the lowest months. Those are among Yekaterinburg's wettest months, with about 80 mm of rain a month against 25 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Eurasian Baskettail sightings with a recorded time, and about 9 in 10 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 Eurasian Baskettail sightings, Yekaterinburg ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Kyiv (Ukraine, under 5%) and Nizhny Novgorod (Russia, under 5%).
Same order: Odonata
The closest relatives of the Eurasian Baskettail that you can see in Yekaterinburg (order Odonata, Dragonflies and Damselflies) are Yellow-Winged Darter (about 10%), Black Meadowhawk (about 10%) and Vagrant Darter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eurasian Baskettail is recorded against all the insects logged in Yekaterinburg (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.
