Under 5% of wildlife watchers report a Lythria cruentaria sighting in Helsinki on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 602nd 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 Lythria cruentaria in Helsinki on a given day, against under 5% in August to June, the lowest months.

GBIF citizen-science records
It is estimated from how often the Lythria cruentaria is recorded against all the insects logged in Helsinki (7 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.
