Under 5% of wildlife watchers report a Pale Straw Pearl sighting in Helsinki on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 374th 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.
July and August
In those months about 10% of wildlife watchers report a Pale Straw Pearl in Helsinki on a given day, against under 5% in September to June, the lowest months.

GBIF citizen-science records
It is estimated from how often the Pale Straw Pearl is recorded against all the insects logged in Helsinki (14 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.
