Explanation of Names
"The feeding activities of cotton stainers on cotton produce a stain on the lint which reduces its value. A few authorities have reported the stain comes from excrement of the bugs. However, most have stated that the stain primarily is a result of the bug puncturing the seeds in the developing bolls causing a juice to exude that leaves an indelible stain. Feeding by puncturing flower buds or young cotton bolls usually causes reduction in size, or the fruiting body may abort and drop to the ground." - University of Florida
