Brachymyrmex is a genus of ants in the subfamily Formicinae, commonly referred to as rover ants due to their small size and wandering behavior. Brachymyrmex ants are very small, with workers typically measuring between 1.5 to 2.5 mm in length. Brachymyrmex ants are omnivorous, feeding on a variety of food sources including sweets, proteins, and liquids such as honeydew produced by aphids and other sap-sucking insects.



Diet

  • Omnivorous, feeding primarily on honeydew produced by aphids, scale insects, and mealybugs.

  • Also consume floral nectar, extrafloral nectar, pollen, fungi, dead insects, and other small arthropods.

  • Workers readily scavenge sugary foods and are frequent visitors to fruit, sap flows, and human food sources.

Range

  • The genus Brachymyrmex is distributed from the southern United States through Mexico, Central America, the Caribbean, and much of South America.

  • In Mexico, numerous species occur on both the Pacific and Gulf slopes, including Guerrero and the Zihuatanejo region.

  • Found from sea level to over 2,500 m (8,200 ft), depending on the species.

Habitat

  • Inhabits tropical dry forests, tropical rainforests, pine-oak forests, grasslands, mangroves, agricultural land, gardens, and urban areas.

  • Nests in soil, leaf litter, beneath stones, under loose bark, inside rotting logs, and occasionally within buildings.

  • Colonies are often associated with plants hosting honeydew-producing insects.

Size

  • Worker length: 1–3 mm (0.04–0.12 in)

  • Queen length: 3–5 mm (0.12–0.20 in)

  • Colonies typically contain several hundred to several thousand workers, although some species form much larger colonies.
