Rare
Under 5% of wildlife watchers report a Dusky Cockroach 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 June
In those months about 10% of wildlife watchers report a Dusky Cockroach in Wadden Sea National Park on a given day, against under 5% in April–May and July–February, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Dusky Cockroach sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 parks where we can rate Dusky Cockroach sightings, Wadden Sea National Park ranks 4th at under 5%. The best odds are in Cape Breton Highlands National Park (Canada, about 10%), Acadia National Park (United States, about 10%) and Bavarian Forest National Park (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the Dusky Cockroach 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.
