Rare
Under 5% of wildlife watchers report a Tree Damsel Bug sighting in Vienna on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 399th 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.
June and July
In those months about 10% of wildlife watchers report a Tree Damsel Bug in Vienna on a given day, against under 5% in August to May, the lowest months. Those are among Vienna's wettest months, with about 90 mm of rain a month against 40 mm in February.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Tree Damsel Bug sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 20
Of the 20 cities where we can rate Tree Damsel Bug sightings, Vienna ranks 9th at under 5%. The best odds are in Berlin (Germany, about 10%), Kharkiv (Ukraine, about 10%) and Kyiv (Ukraine, about 10%).
GBIF citizen-science records
It is estimated from how often the Tree Damsel Bug is recorded against all the insects logged in Vienna (34 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.
