Myrmicaria brunnea

A large, robust ant that punches above its difficulty rating, brunnea founds with several queens and scales up on a broad base, so a starter colony soon turns into a real eye-catcher. It is an Indian tropical species and wants steady warmth and high humidity, conditions that are easy to set and hold. What makes it such a good first ant is its toughness: it grows readily and shrugs off the minor mistakes that come with learning. It carries a mild sting as well as a bite, so handle the arena sensibly, but beyond that it is a forgiving, productive colony to cut your teeth on.

An omnivore that runs the workforce on sugars and the brood on protein. These big foragers drink sweet liquids freely and carry insect prey back to the larvae. Keep sugar available and serve protein two or three times a week.

Raise the founding queen in a test tube, then move to a generous humid nest as soon as workers cover the floor; this big-bodied tropical species expands quickly and needs room early. Choose a Ytong, 3D-printed or hybrid nest that holds moisture, with a wet chamber and a drier corner so brood can be placed correctly. Seal the arena rim with fluon (PTFE), oil, or talc and water. An ANTonTOP formicarium or starter kit supplies the roomy humid nest, arena and escape barrier as a matched set.

A tropical ant that wants steady heat, so keep the nest at 24-27 °C and the arena at 25-29 °C. Hold humidity high, 65-80% in the nest and 55-70% in the arena. Warm one end only so the colony can pick its spot. No hibernation applies, so keep it active and fed all year.

Several queens and a reliable brood cycle build the colony steadily toward up to 10,000 workers, so give a large genus like this room to expand. Your colony arrives as a queen or queens with workers and brood.

• The downward-hooked gaster is the genus signature, letting Myrmicaria aim their defensive spray and sting backward at whatever is bothering them.
• This is a widespread and abundant ant across the Indian subcontinent and Southeast Asia, often one of the most obvious soil-nesting ants on the ground.
• Disturb a nest and the workers release a strong, sharp-smelling alarm secretion that recruits nestmates and deters attackers.
• Polygyny is common in the genus, and multiple egg-laying queens are the engine behind colonies that reach into the thousands.

Is Myrmicaria brunnea good for beginners?

Yes. It is rated Beginner, sturdy and forgiving, a great first colony.

Does this tropical Indian ant need a winter rest?

No. It is tropical and stays active all year, no winter rest needed.

Does Myrmicaria brunnea sting?

Yes, it has a sting along with a mild bite, so handle the arena with care.

How large can a brunnea colony get?

Up to 10,000 workers.

How big is the queen and how big are the workers?

The queen measures 12-16 mm, with workers at 5-9 mm.

How fast does it grow?

Growth is reliable for this large genus and is helped by the multiple queens.

What does it eat?

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

Will it arrive alive?

Yes. It ships with workers and brood, plus a heat or cool pack, sent within 24 h 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.
