Rare
Under 5% of wildlife watchers report a Tree-Lichen Beauty sighting in Vienna on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 378th 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 Tree-Lichen Beauty 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 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Tree-Lichen Beauty sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
8th of 16
Of the 16 cities where we can rate Tree-Lichen Beauty sightings, Vienna ranks 8th at under 5%. The best odds are in Sofia (Bulgaria, about 10%), Kharkiv (Ukraine, about 10%) and Budapest (Hungary, about 10%).
GBIF citizen-science records
It is estimated from how often the Tree-Lichen Beauty is recorded against all the insects logged in Vienna (39 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.
