Sweep-net collections of Spanogonicus albofasciatus (Reuter) and Rhinacloa forticornis Reuter on cotton in 3 different years showed that S. albofasciatus was dominant in all years with its seasonal peak larger than and preceding that of R. forticornis. R. forticornis appeared to be a predator. Both species were abundant on weeds in cottonfields without being abundant on cotton itself. In cage tests the cotton plants easily tolerated feeding damage by S. albofasciatus and recovered quickly. Square shedding in the presence of this insect should probably be attributed to lygus bugs or to physiological causes. Test results indicated that natural populations would rarely damage cotton except in the seedling stage. A low reproductive rate of S. albofasciatus on Acala 4–42, Acala 44, and Deltapine Smoothleaf 3798 cotton varieties is suggested.
