Oecophylla longinoda

Few ants put on a display like weavers: workers chain their bodies together to haul leaf edges into place, then use their own larvae as living glue guns, squeezing them to release silk that binds the leaves into an aerial nest. The colony lives in the trees rather than the ground and grows to a vast population under one queen. That arboreal lifestyle and the large appetite are exactly what make it a Crazy-difficulty, expert-only species, unsuitable for a first colony. For a keeper who has kept ants before and wants a centrepiece that behaves like nothing else in the hobby, longinoda rewards the effort.

A canopy omnivore that patrols leaves for live prey and tends sap-feeding insects for honeydew. Keep a sugar source always available for the huge worker force, and offer protein two to three times a week to drive the brood.

Weavers nest in the canopy, not the soil, so skip ground chambers. Found a young colony in a small arena with a test tube or a compact ANTonTOP starter kit, then move up to a tall, planted arena or a vertical formicarium with branches and live or artificial foliage to anchor its silk nests. Keep height, warmth and moisture as the colony grows. These are superb climbers and escape artists, so seal every seam and run a dependable barrier, fluon (PTFE) on smooth walls, or oil where PTFE will not stick. ANTonTOP supplies the vertical arena, foliage anchors and barrier as a set.

An arboreal tropical species that wants steady warmth and moisture. Run the nest at 25-28 °C and the arena at 25-30 °C, with nest humidity 65-80% and arena humidity 55-70%. Warm one side with a cable or mat so the colony can pick its spot rather than baking the whole enclosure. There is no hibernation: keep it warm, humid and fed all year.

A weaver colony starts slowly while the queen raises her first silk-spinning workers, with the first appearing about 30 days after a clutch of roughly 4 eggs is laid, then accelerates hard and can climb toward 500,000 workers in maturity. Have height and foliage ready well ahead of the surge. You receive a queen with workers and brood to anchor the first silk nest.

• Weaver ants build their nests by holding wriggling larvae in their jaws and using them as living glue guns, dabbing out silk that no adult worker can produce.
• To pull leaf edges together, workers link legs into living chains and haul as a team, then hold the gap closed while others sew.
• The colony spreads across many leaf nests in several trees yet answers to a single queen, defending the whole territory as one.
• African farmers have long used weaver ant colonies as natural pest control in tree crops, one of the oldest known forms of biological control.

Is Oecophylla longinoda good for beginners?

No, it is a Crazy-level, arboreal species with a large appetite and strong escaping skills, best for keepers who already have experience.

Does the African weaver ant need a winter rest?

No. It is tropical and stays active all year, so keep feeding and do not lower the temperature.

Does the weaver ant sting or bite?

It has no sting, but it bites painfully and sprays formic acid when defending the colony.

How big can the colony get?

Up to 500,000 workers under good conditions.

How big is the queen?

The queen is 12-16 mm; workers are 4-9 mm and majors reach 8-10 mm.

How quickly does a weaver colony build?

Slow at first. The first workers appear about 30 days after eggs are laid, then it speeds up considerably.

What do weaver ants feed on?

Sugar water or nectar/jelly plus live insects such as crickets and flies; it readily takes both.

How is it shipped and will it arrive alive?

You get a queen with workers and brood plus a heat or cool pack, dispatched within 24 h with tracking to keep transit short and safe.

Escape prevention. Coat the inner rim of every open arena with fluon (PTFE), or use talc-and-water or an oil barrier as a backup, and keep a tight, fine-mesh lid on top. Check the barrier regularly, since dust, condensation and feeding debris break a fluon line over time. Keep tubing connectors tight and seal any gaps in the nest.

Keeping reminders. Always offer fresh water and never let the nest dry out completely. Give carbohydrates continuously and protein a few times a week, and remove uneaten insect prey within 24 hours before it moulds. Keep the formicarium out of direct sunlight and away from constant vibration, which stresses a young colony. A water-filled test tube plugged with cotton makes an ideal spare incubator whenever you need one.

Before you buy – do not rehouse too early. Have a test-tube setup or a small formicarium with an outworld and a working barrier ready before your colony arrives. A founding colony grows slowly at first, which is normal. Moving a small colony into a large nest too soon invites mould, mites and stress, and the workers die off one by one. Keep the colony in its open test tube on the arena, plug the nest entrance with cotton, and open up the next chambers only once the colony fills roughly 10-15% of the space.

What we ship. Every colony ships with a live-arrival guarantee, backed by our 24h unboxing-video guarantee: if the queen does not arrive alive, we reship free. Parcels travel with DHL, InPost (PL) or EMS, with a heat or cold pack to suit the season, packed discreetly and securely. We ship across the EU and worldwide, with free shipping over the Europe threshold.
