Pyrrhocoridae

Definition

A family of true bugs (Hemiptera: Heteroptera: Pentatomomorpha) comprising more than 300 species worldwide, commonly known as red bugs or firebugs for their frequently aposematic red-and-black coloration. The family includes economically significant pests such as cotton stainers (Dysdercus spp.), whose feeding damages cotton fibers and leaves indelible yellow-brown stains. Pyrrhocoridae are distinguished from the superficially similar Lygaeidae by the absence of ocelli on the vertex.

Etymology

From Pyrrhocoris (type genus, from Greek pyrrhos 'flame-colored, red' + koris 'bug') + Latin -idae (family suffix).

Example

The firebug Pyrrhocoris apterus, a common Palearctic species, serves as a model organism for studies of wing polymorphism and reproductive physiology, while Dysdercus suturellus is a major cotton pest in the New World.

Synonyms

• red bugs (common name)
• firebugs (common name, partial)

Related Terms

• Hemiptera
• Heteroptera
• Pentatomomorpha
• Lygaeidae
• Dysdercus
• ocelli
• Cotton stainer
• true bugs

Usage Notes

Not to be confused with Lygaeidae (seed bugs), which share similar coloration but possess ocelli; the ocellar character provides rapid field separation. The common name 'cotton stainer' applies specifically to Dysdercus and related genera, not the entire family. Some authors historically treated Pyrrhocoridae as a subfamily of Lygaeidae, but modern classification recognizes them as distinct families.
