Cottonseed bug
Oxycarenus luctuosus

Adults are 4 mm long and are black and white with wings folded flat on the back. Wings are mostly clear with black markings. Nymphs are bright red.

Adults and nymphs feed on seeds of open bolls, resulting in a reduction of seed weight and seed viability in late bolls. The eggs are laid in open bolls and the bright red nymphs can be found in clusters among the lint.
