The firebug, Pyrrhocoris apterus, is a common insect of the family Pyrrhocoridae. 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). Pyrrhocoris apterus is distributed throughout the Palaearctic from the Atlantic coast of Europe to northwest China. 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 →

Possible
About 30% of wildlife watchers report a European Firebug sighting in Bucharest on a given day, based on 179 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 361 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
March and September
In those months about 40% of wildlife watchers report a European Firebug in Bucharest on a given day, against about 10% in December, the lowest month.
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.
21st of 61
Of the 61 cities where we can rate European Firebug sightings, Bucharest ranks 21st at about 30%. The best odds are in Dushanbe (Tajikistan, about 60%), Bishkek (Kyrgyzstan, about 50%) and Kyiv (Ukraine, about 50%).
Same order: Hemiptera
The closest relatives of the European Firebug that you can see in Bucharest (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Southern Green Stink Bug (about 20%), Mediterranean Spiny Stink Bug (about 20%) and Brown Marmorated Stink Bug (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the European Firebug is recorded against all the insects logged in Bucharest (179 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.
