In 3 days ~10% in a week ~20%
Oberea linearis is a species of beetle in the family Cerambycidae. It was described by Carl Linnaeus in 1761, originally under the genus Cerambyx. It has a wide distribution throughout Europe. It is preyed upon by Opilo pallidus, and serves as a host for the parasitic wasp species Dolichomitus messor and Phaenolobus terebrator. It feeds on Juglans regia, Corylus avellana, Ulmus glabra, Ostrya carpinifolia, and Carpinus betulus. It contains the varietas Oberea linearis var. parallela.
Oberea linearis measures between 11 and 14 mm (0.43 and 0.55 in). Wikipedia →

Rare
Under 5% of wildlife watchers report an Oberea linearis sighting in Copenhagen on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 376th 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 20%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report an Oberea linearis in Copenhagen on a given day, against under 5% in July to May, the lowest months.
Only Copenhagen, in our data
Copenhagen is the only city on Wallace's Line with enough records to rate Oberea linearis sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cerambycidae
The closest relatives of the Oberea linearis 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 Oberea linearis is recorded against all the insects logged in Copenhagen (6 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.
