Acrobat Ant

Acrobat Ants

Introduction:  Acrobat ants include several species. Their common name is descriptive of this ant’s habit of raising the abdomen over the thorax and head, especially when disturbed.

Recognition:  Workers monomorphic, about 1/16-1/8” (2.5-4mm) long; queens range up to 3/8” long. Color light brown to black, sometimes multicolored. Antenna 11-segmented, with 3-segmented club. Thorax with 1 pair dorsal spines.

Habits:  Inside structures, acrobat ants typically nest in wood which has been subjected to high moisture and fungal decay, the same wood conditions favored by carpenter ants. Similarly, they will nest in Styrofoam insulation panels and in wall voids. Outside, most species nest under rocks, or in logs, firewood, or trees where decay enables them to tunnel under the bark and/or into the wood. They occasionally will nest in abandoned termite and carpenter ant galleries as well as in old wood borer, powderpost beetle, or wood wasp tunnels.
