Polyrhachis furcata

Furcata has the full spiny-ant appeal, the hooked, armoured body that makes the genus such a favourite to watch, paired with a steady temperament that never overwhelms. It is a forgiving species to start with, slow enough that you can keep up while you learn the tropical routine. Native to Indonesian rainforest, it stays active all year with no cold rest to manage, so the colony keeps ticking over. If you want an ant that looks dramatic but behaves itself, this is a solid first colony.

Furcata feeds like a typical arboreal Polyrhachis, taking sweet liquids to power the workers and insect protein to push brood growth. A steady sugar source plus protein two or three times a week keeps the colony developing at a healthy clip.

Begin a young colony in a test tube or compact starter nest, letting the workers keep a single chamber damp while brood builds. Upgrade once the first nanitics cover the floor and the nest fills. A humid nest in aerated ytong or acrylic suits these arboreal ants far better than a dry block. Dress the arena rim well with fluon (PTFE), oil, or talc and water, as this is a strong climber that finds any gap. ANTonTOP formicaria and starter kits arrive as a matched humid nest, arena and barrier, ready from day one.

Run a heat cable or mat at one end only so the colony can pick a warm or cool spot along the gradient. Hold the nest at 20-26 °C and the arena at 22-32 °C, with nest humidity at 55-70% and the arena drier at 40-60%. There is no hibernation; as a tropical species it stays active and fed all year.

Polyrhachis build at a slow, steady pace, working toward a final colony of 500-5000 workers over time. You receive a queen with workers and brood, ready to continue in a humid nest paired with a roomy arena.

• The species name furcata means ‘forked’, a nod to the paired, branching spines that armour the body and waist.
• Polyrhachis larvae spin silk, and many species in the genus weave it into nests among leaves and bark rather than digging into soil.
• All members are stingless formicines, defending themselves with formic acid, strong mandibles and their spines.

Is Polyrhachis furcata good for beginners?

Yes. It is rated Beginner, single-queen and slow-paced, so it forgives early mistakes.

Does Polyrhachis furcata need a winter rest?

No. It is tropical and stays active all year with no cold rest needed.

Does furcata sting or bite?

No. It has no sting and only a mild bite.

How big does a furcata colony get?

Up to 500-5000 workers over time.

How big is the furcata queen?

About 11 mm, with workers at 6-9 mm.

How fast does it grow?

Slowly and steadily. Expect gradual growth rather than a population spike.

What does this forked-spine ant eat?

Sugar water or nectar for energy, plus insects like crickets and flies for protein.

Will it arrive alive?

Yes. We ship a queen with workers and brood, with a heat or cool pack, dispatched within 24 h with tracking.

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.
