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). 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.
