With luck
About 10% of wildlife watchers report a Virgin Pigmy sighting in Helsinki on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 307th most-seen of the 838 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
October
In that month about 30% of wildlife watchers report a Virgin Pigmy in Helsinki on a given day, against under 5% in November to August, the lowest months.
Only Helsinki, in our data
Helsinki is the only city on Wallace's Line with enough records to rate Virgin Pigmy sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Virgin Pigmy is recorded against all the insects logged in Helsinki (19 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.
