Paratrechina longicornis, commonly known as the longhorn crazy ant, is a species of ant known for its erratic movement and long antennae. They have very long antennae relative to their body size, which helps distinguish them from other ant species. They are called "crazy ants" because of their quick and irregular movements when foraging. They don't follow a straight path like other ants. Paratrechina longicornis is an omnivorous ant, feeding on a variety of foods, including sweets, proteins, and grease. They are opportunistic scavengers and predators.



Diet

  • Omnivorous, feeding on nectar, honeydew from aphids, scale insects, and mealybugs, as well as dead insects, small arthropods, seeds, fruit juices, fungi, and human food scraps.

  • Workers readily scavenge a wide variety of foods and also prey on small invertebrates.

  • Frequently tend sap-feeding insects in exchange for their sugary honeydew.

Range

  • Believed to have originated in either Africa or tropical Asia, but now found throughout tropical and subtropical regions worldwide.

  • Widespread throughout Mexico, including the Pacific coast of Guerrero and the Zihuatanejo region.

  • One of the world's most successful invasive ant species, commonly associated with ports, cities, and disturbed habitats.

Habitat

  • Occupies tropical dry forests, tropical rainforests, mangroves, agricultural land, gardens, parks, beaches, hotels, and urban areas.

  • Nests in soil, leaf litter, beneath rocks, under logs, inside rotting wood, wall voids, potted plants, and buildings.

  • Colonies frequently relocate to new nesting sites when disturbed.

Size

  • Worker length: 2.5–3.0 mm (0.10–0.12 in)

  • Queen length: 4–5 mm (0.16–0.20 in)

  • Colonies typically contain thousands to tens of thousands of workers and often multiple queens.
