Tetraponera rufonigra

This is one of the most striking twig ants in the hobby, a long-bodied red-and-black hunter that nests up in wood and stems across South and Southeast Asia. It runs on several queens, forages hard through the day, and carries a sting that is properly painful rather than a token defence. That combination of size, attitude and arboreal habit puts it firmly at the top of the difficulty scale. It is for the keeper who wants a demanding, high-impact colony and has the experience to handle it safely.

A large arboreal omnivore that hunts by sight along branches. Quick, sharp-eyed workers run down sugars from nectar and honeydew and take live insect prey to fuel the brood inside their stem nest. Keep a sugar source available and offer protein two to three times a week.

★★★ readily · ★★ moderately · ★ occasionally · ✗ not eaten

A large, strongly stinging canopy ant that wants warmth, height and real moisture. Give it a cork or hardwood module with narrow drilled galleries set upright, since hollow-stem cavities suit it far better than a flat nest, and keep humidity high in the chambers. Upgrade as the colony outgrows each cavity, and never open the setup without the arena sealed first, given the sting. Keep a dependable fluon (PTFE), oil, or talc and water edge on a tall arena. ANTonTOP formicaria and starter kits can be configured for the height, wood and humidity this twig ant demands.

No winter rest applies, since this is a year-round tropical ant. Hold the nest at 24 to 27 °C and the arena at 25 to 29 °C on a warm gradient. This species wants it humid: keep the nest at 70 to 85% and the arena at 60 to 75%, well above what most ants need. Keep warmth and moisture steady, and feed through every season to suit a demanding canopy hunter.

Growth is slow to moderate, with brood taking about 8 to 13 weeks, roughly 2 to 3 months, to develop, building toward as many as 500 large workers. This is a colony that rewards a patient, careful keeper. You receive a queen with workers and brood, ready for a tall, humid, wood-based setup behind a secure barrier.

• The sting of Tetraponera rufonigra is medically notable across South and Southeast Asia, with documented cases of severe allergic reactions, so it is strictly an observe-only ant.
• It belongs to the Pseudomyrmecinae, slender arboreal ants with large eyes and fast, visually guided reactions unlike most soil-dwelling species.
• Workers forage by day along branches and trunks, using keen vision to hunt live prey, which is unusual among ants that mostly rely on scent.

Is Tetraponera rufonigra good for beginners?

No, it is rated Pro, with a painful sting and demanding tropical needs that suit only experienced keepers.

Does Tetraponera rufonigra need a winter rest?

No, it is tropical and stays active year-round.

Does this twig ant sting or bite?

Yes, it has a painful sting, so this is a hands-off, observe-only species.

How big can the colony get?

Up to 500 workers of large-bodied ants.

How big is the queen?

A large 12-16 mm, with workers at 10-12 mm.

How quickly does the colony build up?

Slowly. Brood takes about 2-3 months (8-13 weeks) from egg to adult.

What do Tetraponera rufonigra eat?

Sugar water and nectar or jelly plus insects like crickets and flies; it does not take seeds.

How is it shipped and will it arrive alive?

The queen, workers and brood travel with a heat pack, sent within 24 hours with tracking for a safe, live arrival.

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.
