Easily recognisable due to its striking red and black coloration, it may be confused with the similarly coloured though unrelated Corizus hyoscyami (cinnamon bug or squash bug).

Beyond its native Palaearctic range, it has been recorded in the United States, Central America, Southern Ontario (As an invasive species), India, and Australia. It has been reported as recently expanding its distribution northwards into mainland United Kingdom and eastward on to the coast of the Mediterranean Sea. It is frequently observed to form aggregations, especially in immature forms, containing tens to perhaps a hundred individuals.
The firebug generally mates in April and May. Its diet consists primarily of seeds from lime trees and mallows (see below). It can often be found in groups near the base of lime tree trunks, on the sunny side. The firebug can be seen in tandem formation when mating, which can last from 12 hours up to 7 days. It has been proposed that this long copulation duration... Wikipedia →

Likely
About 40% of wildlife watchers report a European Firebug sighting in Triglav National Park on a given day, based on 69 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 260 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
March
In that month about 70% of wildlife watchers report a European Firebug in Triglav National Park on a given day, against about 10% in November to January, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most European Firebug sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 14 parks where we can rate European Firebug sightings, Triglav National Park ranks 2nd at about 40%, level with the leaders once rounded. The best odds are in Gauja National Park (Latvia, about 40%).

GBIF citizen-science records
It is estimated from how often the European Firebug is recorded against all the insects logged in Triglav National Park (69 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.
