Corizus hyoscyami is a species of scentless plant bug belonging to the family Rhopalidae, subfamily Rhopalinae. It is commonly called the cinnamon bug or black and red squash bug. Corizus hyoscyami hyoscyami (Linnaeus, 1758)
Corizus hyoscyami nigridorsum (Puton, 1874) Corizus hyoscyami subs. hyoscyami is found in most of Europe; in Britain, the species appears to be spreading northwards, having been recorded in Yorkshire. Corizus hyoscyami subs. nigridorsum is present in Spain, Italy, Morocco and Tunisia.
Adults of Corizus hyoscyami are about 9 millimetres (0.35 in) long. Like all scentless plant bugs, it lacks well-developed scent glands and can be distinguished by numerous veins in the membrane of the hemelytra, characteristic of all members of the Rhopalidae.
In Corizus hyoscyami subs. hyoscyami the third and fourth abdominal tergites are red, while in Corizus hyoscyami subs. nigridorsum they are completely black. The dorsum colours are visible in elitrale transparency under the membrane.
Although striking in colour, Corizus hyoscyami may be confused with the similarly marked but unrelated Pyrrhocoris apterus (firebug) (see comparison... Wikipedia →

Possible
About 20% of wildlife watchers report a Spotted Firebug sighting in Sierra Nevada National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 92nd most-seen of the 479 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June and July
In those months about 30% of wildlife watchers report a Spotted Firebug in Sierra Nevada National Park on a given day, against under 5% in September to April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Spotted Firebug sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 9 parks where we can rate Spotted Firebug sightings, Sierra Nevada National Park has the highest daily chance: about 20%. Next come Vanoise National Park (France, about 20%) and Cévennes National Park (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Spotted Firebug is recorded against all the insects logged in Sierra Nevada National Park (17 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.
