Rare
Under 5% of wildlife watchers report a Dark Bordered Pearl 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.
September
In that month about 10% of wildlife watchers report a Dark Bordered Pearl in Helsinki on a given day, against under 5% in October to August, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Dark Bordered Pearl sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
3rd of 3
Of the 3 cities where we can rate Dark Bordered Pearl sightings, Helsinki ranks 3rd at under 5%. The best odds are in Copenhagen (Denmark, about 10%) and London (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Dark Bordered Pearl 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.
