With luck
About 10% of wildlife watchers report a Dusky Cockroach sighting in Berlin on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 343rd most-seen of the 1065 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 and July–August
In those months about 10% of wildlife watchers report a Dusky Cockroach in Berlin on a given day, against under 5% in June and September–April, 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.
Among the best
Of the 11 cities where we can rate Dusky Cockroach sightings, Berlin ranks 6th at about 10%, level with the leaders once rounded. The best odds are in Warsaw (Poland, about 10%), Helsinki (Finland, about 10%) and Stockholm (Sweden, about 10%).
GBIF citizen-science records
It is estimated from how often the Dusky Cockroach is recorded against all the insects logged in Berlin (22 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.
