Foraging Characteristics: Medium sized, pale orange to dark brown, slender and elongate ant. Foraging singly, moving quickly. Nest is distinctive cone-shaped mound in sandy soil. Ant does not sting or act aggressively. Nests not large. Workers have strong odor when crushed described by some as rotting coconuts.

Diet:  Hunt live insects, including winged fire ants. Collect honeydew from sap-sucking insects.

Detailed Description: 2-4 mm  (1/12–1/6 in) long. Integument thin. Twelve-segmented antennae. Propodeum bearing a tooth-like protuberance projecting vertically in side view. Ventral surface of head with a few very long, curved hairs, used for carrying pellets of damp sand. Subfamily Dolichoderinae.
