Rare
Under 5% of wildlife watchers report a Wolff's Groundbug sighting in Helsinki on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 665th 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.
August
In that month about 10% of wildlife watchers report a Wolff's Groundbug in Helsinki on a given day, against under 5% in September to July, the lowest months.
Only Helsinki, in our data
Helsinki is the only city on Wallace's Line with enough records to rate Wolff's Groundbug sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Wolff's Groundbug is recorded against all the insects logged in Helsinki (6 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.
