Rare
Under 5% of wildlife watchers report a Yellow Oak Button sighting in Helsinki on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 732nd most-seen of the 838 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.
July
In that month about 10% of wildlife watchers report a Yellow Oak Button in Helsinki on a given day, against under 5% in August to June, the lowest months.
6th of 7
Of the 7 cities where we can rate Yellow Oak Button sightings, Helsinki ranks 6th 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 Helsinki (family Tortricidae, Tortricid Leafroller Moths) are Barred Marble (about 10%), Common Marble (about 10%) and White-Foot Bell (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 Helsinki (5 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.
