Rare
Under 5% of wildlife watchers report a Small Red-Eyed Damselfly sighting in Vienna on a given day, based on 49 verified sightings from GBIF citizen-science data. It is the 416th most-seen of the 1406 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.
July and August
In those months about 10% of wildlife watchers report a Small Red-Eyed Damselfly in Vienna on a given day, against under 5% in September to June, the lowest months. Those are among Vienna's wettest months, with about 85 mm of rain a month against 40 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Small Red-Eyed Damselfly sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
18th of 24
Of the 24 cities where we can rate Small Red-Eyed Damselfly sightings, Vienna ranks 18th at under 5%. The best odds are in Brussels (Belgium, about 10%), Rostov-on-Don (Russia, about 10%) and Jerusalem (Israel, about 10%).
GBIF citizen-science records
It is estimated from how often the Small Red-Eyed Damselfly is recorded against all the insects logged in Vienna (49 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.
