Rover worker ants are small (about 1/16″), uniform in size (monomorphic), and vary in color from black, to dark brown. Colonies are small ranging in from hundreds to a few thousands members. They contain only one queen per colony. Colonies are usually found in the soil or rotting wood but they will nest in potted plants, wall voids and other harborages. Colonies are commonly associated with soil dwelling aphids and mealy bugs that produce honey dew, a sugary liquid extracted from plants on which these sucking insects feed.
