Cotton Stainers, Red Cotton Bugs, Cotton Stainer Bugs
Dysdercus is a widespread genus of true bugs in the family Pyrrhocoridae, commonly called cotton stainers. Species are known for their bright red coloration derived from plant pigments and their economic significance as pests of cotton. The genus can be distinguished from similar families by the absence of ocelli on the head, and from other Pyrrhocoridae genera by prominent white markings at the head-thorax junction and along the thorax sides.
Dysdercus suturellus
Common Cotton Stainer Bug, Cotton Stainer
Dysdercus suturellus is a true bug in the family Pyrrhocoridae, commonly known as the cotton stainer. Adults measure 1–1.5 cm in length with a distinctive red thorax and dark brown wings bearing a yellow cross-shaped pattern. The species is native to the southeastern United States, Jamaica, and Puerto Rico. It is a significant agricultural pest of cotton and related plants, with adults and late-stage nymphs feeding on developing seeds and bolls. The bright red coloration is derived from plant pigments obtained through its diet.
