Rare
Under 5% of wildlife watchers report a White Plume Moth sighting in Helsinki on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 413th 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 White Plume Moth in Helsinki on a given day, against under 5% in September to June, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most White Plume Moth sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
9th of 18
Of the 18 cities where we can rate White Plume Moth sightings, Helsinki ranks 9th at under 5%. The best odds are in Turin (Italy, about 10%), Rotterdam [The Hague] (Netherlands, about 10%) and Warsaw (Poland, about 10%).
GBIF citizen-science records
It is estimated from how often the White Plume Moth is recorded against all the insects logged in Helsinki (12 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.
