With luck
About 10% of wildlife watchers report a Yellow Satin Veneer sighting in Wadden Sea National Park on a given day, based on 32 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 234th most-seen of the 818 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Yellow Satin Veneer in Wadden Sea National Park on a given day, against under 5% in September to May, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Yellow Satin Veneer sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 3 parks where we can rate Yellow Satin Veneer sightings, Wadden Sea National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Bavarian Forest National Park (Germany, about 10%) and Snowdonia National Park (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow Satin Veneer is recorded against all the insects logged in Wadden Sea National Park (32 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.
