Rare
Under 5% of wildlife watchers report a Philopedon plagiatum sighting in Amsterdam on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 194th most-seen of the 234 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.
May
In that month about 10% of wildlife watchers report a Philopedon plagiatum in Amsterdam on a given day, against under 5% in June to April, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Philopedon plagiatum sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 cities where we can rate Philopedon plagiatum sightings, Amsterdam ranks 3rd at under 5%. The best odds are in Rotterdam [The Hague] (Netherlands, about 10%) and Berlin (Germany, about 10%).

GBIF citizen-science records
It is estimated from how often the Philopedon plagiatum is recorded against all the insects logged in Amsterdam (5 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.
