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 →

With luck
About 10% of wildlife watchers report a Spotted Firebug sighting in Bavarian Forest National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 471st most-seen of the 1115 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.
April–May and July–August
In those months about 10% of wildlife watchers report a Spotted Firebug in Bavarian Forest National Park on a given day, against under 5% in June and September–March, 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.
8th of 9
Of the 9 parks where we can rate Spotted Firebug sightings, Bavarian Forest National Park ranks 8th at about 10%. The best odds are in Sierra Nevada National Park (Spain, about 20%), 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 Bavarian Forest National Park (11 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.
