Carebara diversa

This is the marauder ant taken to its limit and a flagship undertaking for any expert. Its caste spread is dramatic, with tiny minors and outsized super-majors patrolling the same trail, and its multi-queen colonies can grow to a scale that dwarfs almost anything else in the hobby. Active day and night, it never really rests. Native to Kerala and the wider South and Southeast Asia, it needs constant heat, high humidity and an ever-expanding home. Rated Pro, it is built for a keeper ready to commit to long-term tropical care and continual space.

A marauder that consumes insect protein on a grand scale to supply its enormous brood, backed by a constant sugar source for the foragers. This colony eats meat heavily, so keep prey coming and the sweet feeder full.

Found this giant in a humid setup and seal every joint, because the minute minors cannot be trusted near a hairline gap. Plan a run of upgrades to ever-larger moisture-holding nests as the population races past the hundreds of thousands toward a million, keeping connections fine and tight. Hold the arena with a fluon (PTFE) band, a fine oil line, or talc and water, and check it often. ANTonTOP formicaria and starter kits deliver humid, securely sealed builds with matched arenas that scale toward a colony this size.

For this tropical heavyweight, keep the nest at 25-28 °C and the arena at 25-29 °C, with nest humidity high at 70-85% and the arena at 50-70%. Heat one side for a gradient so the colony can choose its warmth, and keep the nest steadily moist. There is no hibernation for this tropical ant, so hold conditions stable and feed all year.

Growth starts slow at founding and then turns explosive, with minors emerging in roughly 4 weeks and majors in about 6-7 weeks, building toward over 1,000,000 workers. The queens can live 10-15 years, so this is a long-term colony. It arrives as a fertilised queen with workers and brood already underway.

• Carebara diversa is the largest of the marauder ants, with super-soldiers whose massive heads dwarf the pinhead-sized minors of the same nest.
• Its mass raids were documented in detail by biologist Mark Moffett, who filmed columns swarming and butchering prey far larger than any single ant.
• The minute minors frequently hitch rides on the bodies of larger nestmates and on hauled food, a hallmark of marauder traffic.
• It was long known under the name Pheidologeton diversus before the group was merged into Carebara.

Is Carebara diversa good for beginners?

No, it is rated Pro and needs long-term tropical care, so it is for expert keepers.

Does Carebara diversa need a winter rest?

No, this tropical marauder takes no hibernation; keep it warm and humid year-round.

Does Carebara diversa sting or bite?

Yes, its sting can cause moderate pain, so handle with care.

How huge can a Carebara diversa colony get?

Over 1,000,000 workers over time.

How large is the queen?

Each queen measures 18-24 mm, and there can be two or more.

How fast does it grow?

Slow at founding, then explosive; minors hatch in roughly 4 weeks and majors in about 6-7 weeks.

What does it eat?

Heavy insect protein for the brood plus a constant sugar source.

Will it arrive alive?

Colonies ship with a queen, workers and brood plus a heat or cool pack, dispatched within 24 hours 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.
