Ectatomma ruidum is a species of ant in the subfamily Ectatomminae, found primarily in Central and South America. Ectatomma ruidum is a generalist forager, meaning it feeds on a variety of food sources. This can include small insects, nectar, and seeds. They also engage in cleptobiosis, where they steal food from other insect colonies.



Diet

  • Predatory and scavenging, feeding on termites, ants, beetles, caterpillars, flies, spiders, grasshoppers, and other arthropods.

  • Also consumes nectar, honeydew, fallen fruit, and carrion when available.

  • Workers hunt individually rather than recruiting nestmates, using their powerful mandibles and venomous sting to subdue prey.

Range

  • Native to Mexico, Central America, the Caribbean, and northern South America.

  • In Mexico, it is widespread along both the Pacific and Gulf slopes, including Guerrero and the Zihuatanejo region.

  • Common in tropical lowland habitats from sea level to about 1,500 m (4,900 ft).

Habitat

  • Inhabits tropical dry forests, tropical rainforests, secondary forests, forest edges, grasslands, plantations, agricultural fields, and gardens.

  • Nests in soil, usually beneath stones, logs, leaf litter, or at the base of trees.

  • Frequently forages on the ground in open, sunny areas and along forest trails.

Size

  • Worker length: 8–12 mm (0.3–0.5 in)

  • Queen length: 12–15 mm (0.5–0.6 in)

  • Colonies are relatively small, typically containing 50–500 workers.
