Rare
Under 5% of wildlife watchers report a Rust Pine Borer sighting in Copenhagen on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 280th most-seen of the 476 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 Rust Pine Borer in Copenhagen on a given day, against under 5% in September to June, the lowest months.
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.
Yes
Of the 3 cities where we can rate Rust Pine Borer sightings, Copenhagen has the highest daily chance: under 5%. Next come Helsinki (Finland, under 5%) and Vienna (Austria, under 5%).
Same family: Cerambycidae
The closest relatives of the Rust Pine Borer that you can see in Copenhagen (family Cerambycidae, Longhorn Beetles) are Wasp Beetle (about 10%), Red Pine Longhorn Beetle (about 10%) and Tanbark Borer (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 Copenhagen (9 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.
