Oecophylla smaragdina (Australia)

Weaver ants are arboreal and build massive colonies in the canopy of tropical forests across Asia and Australia. A single colony can span dozens of trees and include hundreds of thousands of workers. The nests are constructed from leaves that are pulled together and “stitched” using silk produced by larvae.

Workers forage both in the trees and on the ground, feeding on live prey such as insects, as well as honeydew from aphids and scale insects. These ants are polygyne, meaning multiple queens can coexist in a single colony. The species communicates using a complex system of pheromones, touch, and visual cues, and will fiercely defend their territory from intruders.

At Esthetic Ants, you can obtain healthy, active colonies of Oecophylla smaragdina. Each colony includes a fertile queen, a group of workers, and developing brood. When you purchase from Esthetic Ants, you’re investing in a species that is not only biologically fascinating but also a true display piece for any ant enthusiast.

Due to their territorial behavior and large size, they are best suited for intermediate to advanced keepers who can meet their special environmental and spatial needs.

Keeping Oecophylla smaragdina requires a vertical formicarium or naturalistic setup with live plants to allow nest-building. These ants do not tolerate disturbance well and need high humidity in the nest (70–90%) and moderate humidity in the arena (50–70%). Nest temperatures should stay between 24–28°C and the arena can range from 21–30°C.

Feeding includes honey water, fruit (such as grapes), and protein sources like flies or crickets. Because of their large colony size, they consume significant amounts of food. Escape prevention is crucial—use tight lids and barriers like fluon or Vaseline, as they are excellent climbers.

Their nests must be misted regularly to maintain humidity and planted with suitable host trees or shrubs (e.g., citrus, ficus). Foragers and workers are aggressive and will bite if threatened, making them effective defenders of their territory—but also requiring careful handling.
