Rare
Under 5% of wildlife watchers report a Gelechia rhombella sighting in Helsinki on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 445th 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 Gelechia rhombella in Helsinki on a given day, against under 5% in September to June, the lowest months.

Of the 2 cities where we can rate Gelechia rhombella sightings, Helsinki has the highest daily chance: under 5%. Next come Moscow (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Gelechia rhombella is recorded against all the insects logged in Helsinki (13 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.
