Dark Rover Ants; Brachymyrmex patagonicus, were milking this Coccoidea for honeydew/excrement from an opening in this white ball-shaped (~2.5 mm round) scale or mealybug attached to the leaf sheath, on a leaf node of a blade of Bermuda grass; Cynodon dactylon. The ants used their antennae to touch something protruding from an opening in the outer waxy coating of the Coccoidea and the insect then pushed out a clear sticky liquid ball the ants were eating/drinking. The insect appears to have a round, dark brown body under the white waxy covering that resembles a tuft of cotton. This was the only Coccoidea insect on the blade of grass. Looks similar to images of a female Antonina graminis; Rhodesgrass mealybug shown here: https://www.inaturalist.org/observations/99776528 and here: https://hgic.clemson.edu/.../bermudagrass-scale.../
