With luck
About 10% of wildlife watchers report a Dark Bordered Pearl sighting in London on a given day, based on 49 verified sightings from GBIF citizen-science data. It is the 477th most-seen of the 1504 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.
June to September
In those months about 10% of wildlife watchers report a Dark Bordered Pearl in London on a given day, against under 5% in October to May, 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.
Among the best
Of the 3 cities where we can rate Dark Bordered Pearl sightings, London ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Copenhagen (Denmark, about 10%).
GBIF citizen-science records
It is estimated from how often the Dark Bordered Pearl is recorded against all the insects logged in London (49 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.
