With luck
About 10% of wildlife watchers report a Philopedon plagiatum sighting in Wadden Sea National Park on a given day, based on 86 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 48th most-seen of the 818 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
April to June
In those months about 20% of wildlife watchers report a Philopedon plagiatum in Wadden Sea National Park on a given day, against under 5% in August to February, the lowest months. Those are among Wadden Sea National Park's driest months, with about 50 mm of rain a month against 140 mm in November.

GBIF citizen-science records
It is estimated from how often the Philopedon plagiatum is recorded against all the insects logged in Wadden Sea National Park (86 verified sightings from 2019 to 2026), 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.
