English: A group of firebugs (Pyrrhocoris apterus) preparing for hibernation. "The firebug, Pyrrhocoris apterus, is a common insect of the family Pyrrhocoridae. Easily recognizable due to its striking red and black coloration, but may be confused with the similarly coloured though unrelated Corizus hyoscyami (cinnamon bug, squash bug) (see comparison). Pyrrhocoris apterus is distributed throughout the Palaearctic from the Atlantic coast of Europe to northwest China. It has also been reported from the US, Central America and India. It has been reported as recently expanding its distribution northwards into mainland UK and eastward on to the coast of the Mediterranean sea. They are frequently observed to form aggregations, especially as immature forms, with from tens to perhaps a hundred individuals. Firebugs generally mate in April and May. Their diet consists primarily of seeds from lime trees and mallows (see below). They can often be found in groups near the base of lime tree trunks, on the sunny side. They can be seen in tandem formation when mating which can take from 12 hours up to 7 days. The long period of copulating is probably used by the males as a form of ejaculate-guarding under high competition with other males." (Wikipedia)
