Rare
Under 5% of wildlife watchers report a Calamobius filum sighting in Vienna on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1286th 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 Calamobius filum 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 Calamobius filum sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Calamobius filum sightings, Vienna ranks 2nd at under 5%. The best odds are in Madrid (Spain, about 10%).
Same family: Cerambycidae
The closest relatives of the Calamobius filum 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 Calamobius filum is recorded against all the insects logged in Vienna (5 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.
