Rare
Under 5% of wildlife watchers report a Dusky Cockroach sighting in Moscow on a given day, based on 36 verified sightings from GBIF citizen-science data. It is the 333rd most-seen of the 1111 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.
June
In that month about 10% of wildlife watchers report a Dusky Cockroach in Moscow on a given day, against under 5% in July to May, 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.
11th of 11
Of the 11 cities where we can rate Dusky Cockroach sightings, Moscow ranks 11th at under 5%. 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 Moscow (36 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.
