Identification: Workers are tiny black or with a reddish thorax and pointed abdomens. Abdomens are often raised. Antenna base (scape) is longer than the head. The end of the thorax has a pair of long spines. The joint (petiole) to the abdomen is considered two segments but they are flattened, and attached to the upper side of the abdomen, rather than in the center as with all other ants. Queens are all reddish to shiny black with three distinct rows of hairs on the abdomen and a pointed tip. Males are small and black with very tiny heads.

Size: Workers and males 2.5 to 4 mm. Queen about 6 mm.

Flight Time: July to October.

Habitat: Forests and prairies, wet meadows. Nests in wood, grass clumps or under rocks.

Food: Honeydew aphids and treehoppers, dead insects, and have been seen building plant fragment tents over the bugs. Also in Eastern Carpenter Bee nests.

Comments: Essex County – Ojibway Prairies. Kent County – Rondeau Provincial Park. Also in Michigan.
