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 →

Rare
Under 5% of wildlife watchers report a Spotted Firebug sighting in Lisbon on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 324th most-seen of the 441 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.
March
In that month about 10% of wildlife watchers report a Spotted Firebug in Lisbon on a given day, against under 5% in April to February, 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.
35th of 35
Of the 35 cities where we can rate Spotted Firebug sightings, Lisbon ranks 35th at under 5%. The best odds are in London (United Kingdom, about 10%), Birmingham (United Kingdom, about 10%) and Algiers (Algeria, about 10%).
GBIF citizen-science records
It is estimated from how often the Spotted Firebug is recorded against all the insects logged in Lisbon (7 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.
