Acrobat
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. Various species are found throughout the United States, including at altitudes of up to 8,000 feet.
Recognition.
Workers monomorphic, about 1/16-1/8" long: queens range up to 3/8" (10 MM) long. Color
light brown to black, sometimes multicolored. Antenna 11 segmented, with 3-segmented club. Thorax with
1 pair dorsal spines. Pedicel 2-segmented, attached to upper side of gaster. Gaster heart-shaped in
dorsal view, broadest toward thorax and sharply pointed at rear. Stinger present. Workers may emit
a repulsive odor when alarmed.
Damage and Sign of Infestation.
Often the only exterior indication of damage is the accumulation of debris expelled by these ants,
especially if the debris is Styrofoam insulation.
They prefer wood softened by decay fungi or Styrofoam insulation, but may enlarge cavities in wood
made by other insect. They will occasionally strip the insulation from electrical or telephone wires
which can cause short circuits.
