The green tropical weaver ant
Oecophylla smaragdina is arguably the most spectacular ant in the world. A bright yellow-green, strictly arboreal, it lives high in the tropical trees of South-East Asia and tropical Australia, where it builds its nests by sewing living leaves together with the silk of its larvae.
The mechanism is extraordinary: several hundred workers pull simultaneously on the edges of neighbouring leaves, forming living worker-to-worker chains. When the edges meet, other workers bring the larvae and press them against the leaves to bond them with silk. The nest takes shape within a few hours.
Watching Oecophylla sew a nest live is probably the most striking experience in amateur myrmecology. The cooperation between hundreds of workers, the use of larvae as living tools, the speed of construction — a true collective genius.
An exceptional social life
Huge colonies: 50,000 to 500,000 workers spread across dozens of neighbouring leaf-nests, on a single tree or several neighbouring trees. The whole thing functions as a coherent superorganism with a single founding queen.
Spectacular defensive behaviour: at the slightest vibration, hundreds of workers pour out of the nests, mandibles open, ready to bite. No serious venom but multiple bites are unpleasant.
Oecophylla = strictly arboreal, so a tall VERTICAL terrarium, with living plants (Ficus, or food-grade plastic imitations), a constant 75-90% humidity, a temperature of 26-32°C, and flight space up high. Very few serious suppliers, complex import. Reserved for the top 1% of the most committed keepers.
Keeping
Humid tropical arboreal: 26-32°C, humidity 75-90%. No hibernation. A vertical terrarium with living plants and anchor points for weaving. Feeding: insects (crickets, roaches), honeydew, fruit. Ventilation mandatory (anti-rot). A lifelong passion species for dedicated myrmecologists.
