Rare
Under 5% of wildlife watchers report a Rust Pine Borer sighting in Vienna on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 1028th 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 Rust Pine Borer in Vienna on a given day, so our monthly data shows no clear season.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Rust Pine Borer sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 3 cities where we can rate Rust Pine Borer sightings, Vienna ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Copenhagen (Denmark, under 5%) and Helsinki (Finland, under 5%).
Same family: Cerambycidae
The closest relatives of the Rust Pine Borer 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 Rust Pine Borer is recorded against all the insects logged in Vienna (10 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.
