Dysdercus is a widespread genus of true bugs in the family Pyrrhocoridae; a number of species attacking cotton bolls may be called "cotton stainers."

Description

Species may be confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli on the head. They can be readily distinguished from most other genera of Pyrrhocoridae by the strong white markings at the junction of the head and thorax, and along the sides of the thorax, and often abdomen.

Ecology

Some members of the genus attack cotton bolls and are known as "cotton stainers."{{cite journal | jstor=24531028 | title=Notes on Trichopodini (Diptera, Larvaevoridae), with description of a new parasite of cotton stainers in Puerto Rico | last1=Sabrosky | first1=Curtis W. |author-link=Curtis Williams Sabrosky | journal=Journal of the Washington Academy of Sciences | date=1950 | volume=40 | issue=11 | pages=361–371 }} There are several species of tachinid flies that are parasitoids of Dysdercus nymphs and have been used as biocontrol agents.{{cite journal | doi=10.1155/1913/43638 | title=Muscoid Parasites of the Cotton—Stainer and Other Lygaeids | date=1913 | last1=Townsend | first1=Charles H.
