With luck
About 10% of wildlife watchers report a Yellow Barklouse sighting in Helsinki on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 345th 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 30%, if each day is a fresh chance.
June and September–October
In those months about 10% of wildlife watchers report a Yellow Barklouse in Helsinki on a given day, against under 5% in July–August and November–May, the lowest months.
Among the best
Of the 21 cities where we can rate Yellow Barklouse sightings, Helsinki ranks 6th at about 10%, level with the leaders once rounded. The best odds are in Hamburg (Germany, about 10%), Leeds (United Kingdom, about 10%) and London (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow Barklouse is recorded against all the insects logged in Helsinki (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.
