Pyrrhocoridae
Pyrrhocoridae is a family of insects with more than 300 species world-wide. Many are red in colour and are known as red bugs, and some species are called cotton stainers because their feeding activities leave an indelible yellow-brownish stain on cotton crops. A common species in parts of Europe is the firebug, and its genus name Pyrrhocoris and the family name are derived from the Greek roots for fire "pyrrho-" and bug "coris". Members of this family are often confused with, but can be quickly separated from, Lygaeidae by the lack of ocelli (simple eyes) on the top of the head.

Odontopus sexpunctatus Dysdercus andreae; Nymphen und adulte Tiere aus Frankreich Die Feuerwanzen (Pyrrhocoridae) sind eine Familie der Wanzen (Heteroptera) innerhalb der Teilordnung Pentatomomorpha.

Pyrrhocoridae is a family of insects with more than 300 species world-wide. Many are red in colour and are known as red bugs, and some species are called cotton stainers because their feeding activities leave an indelible yellow-brownish stain on cotton crops. A common species in parts of Europe is the firebug, and its genus name Pyrrhocoris and the family name are derived from the Greek roots for fire "pyrrho-" and bug "coris". Members of this family are often confused with, but can be quickly separated from, Lygaeidae by the lack of ocelli (simple eyes) on the top of the head.
==Description== The membrane of the forewing has one or two cells from which about 7-8 branching veins emerge that may have branches that fuse together (anastomose) while the main veins reach the margins of the wing. They have three tarsal segments. They can be very difficult to separate from some members of the family Largidae, which also share some of these characters and belong to the same superfamily. Largids tend to have the edge of the pronotum (the top of the first thoracic segment) rounded, but the taxonomic feature for separating them is the found only in females. Female largids have the sixth visible (actually the seventh) abdominal segment appearing to be split in the middle, whereas it is undivided in female pyrrhocorids. A few bugs in the family Rhopalidae have similar colors (e.g., Corizus hyoscyami) but they have ocelli, as do lygaeids.
