Summary

Crematogaster, known as acrobat ants or cocktail ants, are a diverse genus of ants recognized for their unique heart-shaped gaster, arboreal habits, and complex social behaviors. They play significant roles in their ecosystems as predators and mutualistic partners.

Physical Characteristics

Two sizes: workers (2.5-3.5 mm), queens (about twice as long); heart-shaped gaster distinguished by dorsal articulation to the postpetiole.

Identification Tips

Distinguished by a heart-shaped gaster as viewed from above and characteristic raising of the abdomen when alarmed.

Habitat

Found both outdoors in trees and indoors around electrical wires; prefers moist, dark environments including wood collections and under rocks.

Distribution

Cosmopolitan; notably Northern and desert species with a significant presence in the warm, humid Southeast.

Diet

Feeds on honeydew, extrafloral nectar, scavenged protein, carrion, and various insects including wasps and grasshoppers.

Life Cycle

Queen mates during a nuptial flight; can produce unfertilized eggs that become males in absence of a queen.

Reproduction

Nuptial flights occur where queens mate once and retain sperm for life; some large workers can reproduce under certain conditions.

Predators

Other insect species, particularly larger ants or predatory insects that can consume ants.

Ecosystem Role

Participate in mutualism with plants, provide pest control through predation, and contribute to nutrient cycling in their environments.

Cultural Significance

Commonly known as acrobat or cocktail ants due to their distinct behavior and morphology.
