Acrobat ants get their common name from their ability to acrobatically raise their abdomen over their thorax and head, especially when disturbed. There are various species of this ant found throughout the United States, even at altitudes of up to 8,000 feet.
Acrobat ants typically feed on honeydew, a sugary waste excreted by aphids and mealybugs, but they also eat live and dead insects including termite swarmers.
Outside, most species of acrobat ants nest under rocks or in logs, firewood and trees where wood decay allows them to create tunnels. They also build their nests in abandoned cavities carved out by other insects like termites and carpenter ants.
The workers often find a way inside homes by trailing along tree limbs and utility lines, and entering through cracks or holes around window frames, soffits, door thresholds, and other vulnerable spots. Once inside, acrobat ants typically nest in wall voids or wood that has been subjected to high moisture and fungal decay – the same conditions favored by carpenter ants. They have also been known to nest in Styrofoam insulation panels behind siding.
Acrobat ants may bite when threatened. In some species, workers may emit an unpleasant odor when disturbed.
