Rare
Under 5% of wildlife watchers report an Opatrum sabulosum sighting in Wadden Sea National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 699th most-seen of the 818 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.
March and April
In those months about 10% of wildlife watchers report an Opatrum sabulosum in Wadden Sea National Park on a given day, against under 5% in May 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.

Across all the parks we cover, that three-hour window holds the most Opatrum sabulosum sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Opatrum sabulosum sightings, Wadden Sea National Park ranks 3rd at under 5%. The best odds are in Fertő-Hanság National Park (Hungary, about 10%) and Cévennes National Park (France, under 5%).
Same family: Tenebrionidae
The closest relatives of the Opatrum sabulosum that you can see in Wadden Sea National Park (family Tenebrionidae, Darkling Beetles) are Phylan gibbus (about 10%) and Sulphur Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Opatrum sabulosum is recorded against all the insects logged in Wadden Sea National Park (5 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.
