Solenopsis aurea

Colonies are often found under stones (or other objects, such as pieces of wood or cow manure) in loam or coarse gravely soils. Nests may be in the soil, surrounded by a small mound. Dealate females were collected in July and August. (Mackay and Mackay 2002)

Identification
Workers lighter in color with a light colored gaster, often with brown patches. The eyes are small (about 50 ommatidia in the major, 20 in the minor), being separated from the insertion of the mandibles by about twice the maximum diameter of the eyes. The majors have lateral teeth on the clypeus. (Mackay and Mackay 2002)
