Many species of western thatching ant are bi-colored (red and black), but some species can be uniformly brown or black. These large polymorphic ants (4–9 mm) possess a notch or depression on top of the thorax. Many colonies have multiple queens. Colonies usually nest in soil or in rotten logs. Frequently these ants make a thatch or mound of plant material, often grass. They rarely nest in homes, but can still be a problem, as they feed on sweet materials and will also attend aphids for honeydew. Reproductive swarms are produced in late summer to early fall. This group is one of the most abundant and diverse groups of ants; various species occur throughout the Pacific Northwest.
