Remarks
The Cotton Stainer (Dysdercus suturellus) is a pest of cotton crops. "Feeding on the cotton bolls stains them an indelible yellow as plant sap seeps out of the puncture wound, and microorganisms and fungus grows at the site. The feeding habit also damages the fibres by cutting them, and affects the growth of the cotton boll." (From Naturia website; URL below.)
Bugs of this family feed most commonly on wild members of the Mallow family, but more than one species has developed a taste for cotton.
