Rare
Under 5% of wildlife watchers report a Yellow Oak Button sighting in Berlin on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 593rd 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 20%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Yellow Oak Button in Berlin on a given day, against under 5% in July to May, the lowest months.
5th of 7
Of the 7 cities where we can rate Yellow Oak Button sightings, Berlin ranks 5th at under 5%. The best odds are in Liverpool (United Kingdom, about 10%), London (United Kingdom, about 10%) and Essen (Germany, under 5%).
Same family: Tortricidae
The closest relatives of the Yellow Oak Button that you can see in Berlin (family Tortricidae, Tortricid Leafroller Moths) are Clepsis dumicolana (about 10%), Arched Marble (about 10%) and Green Oak Tortrix (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow Oak Button is recorded against all the insects logged in Berlin (17 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.
