Rare
Under 5% of wildlife watchers report an Orchestes quercus sighting in Berlin on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 497th most-seen of the 1065 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.
May and June
In those months about 10% of wildlife watchers report an Orchestes quercus in Berlin on a given day, against under 5% in July to April, the lowest months.
Only Berlin, in our data
Berlin is the only city on Wallace's Line with enough records to rate Orchestes quercus sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Curculionidae
The closest relatives of the Orchestes quercus that you can see in Berlin (family Curculionidae, True Weevils) are Green Immigrant Leaf Weevil (about 10%), Chestnut Weevil (about 10%) and Peritelus sphaeroides (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Orchestes quercus is recorded against all the insects logged in Berlin (18 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.
