Rare
Under 5% of wildlife watchers report a White-Clouded Longhorn Beetle sighting in Vienna on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 838th 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 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-Clouded Longhorn Beetle in Vienna on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most White-Clouded Longhorn Beetle 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 3 cities where we can rate White-Clouded Longhorn Beetle sightings, Vienna ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Kyiv (Ukraine, under 5%) and Paris (France, under 5%).
Same family: Cerambycidae
The closest relatives of the White-Clouded Longhorn Beetle that you can see in Vienna (family Cerambycidae, Longhorn Beetles) are Alpine Longhorn Rosalia (about 10%), Common Grammoptera (about 10%) and Dorcadion aethiops (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-Clouded Longhorn Beetle is recorded against all the insects logged in Vienna (11 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.
