Planuncus tingitanus
In 3 days ~20% in a week ~40%
Planuncus tingitanus s.l. is a working title for any of the species belonging to the Planuncus tingitanus species group, of the cockroach genus Planuncus (Blattodea: Ectobiinae). As the exact status of some the species in this group can not be determined without more research, the whole species complex is referred to by the name of the oldest species in the group sensu lato (hence the "s.l.").
As such, Planuncus tingitanus s.l. refers to an adventive species, or possibly a complex of cryptic species, that has dramatically expanded its range over the southern parts of Northwestern Europe in a very short period of time during the first decades of the 21st century. In Britain it is known as the variable cockroach, due to the variability of its abdominal markings.
The animals spreading across Europe are closely related, or possibly even synonymous to Ectobius perspicillaris tingitanus Bolivar, 1914 (later treated as a species in its own right: Ectobius tingitanus), originally described from the most northern part of Morocco. Furthermore, they cannot be easily distinguished on any constant morphological traits from Ectobius finoti Chopard 1943, described from Algeria... Wikipedia →

With luck
About 10% of wildlife watchers report a Variable Cockroach sighting in Cévennes National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 437th most-seen of the 996 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.
May to November
In those months about 10% of wildlife watchers report a Variable Cockroach in Cévennes National Park on a given day, against under 5% in December to April, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Variable 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.
Yes
Of the 2 parks where we can rate Variable Cockroach sightings, Cévennes National Park has the highest daily chance: about 10%. Next come Pyrénées National Park (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Variable Cockroach is recorded against all the insects logged in Cévennes National Park (15 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.
