Myopias sonthichaiae

Myopias sonthichaiae is a hunter’s ant, and a striking one. The workers and queen are big and dark, so every individual is easy to observe as the colony goes about its predatory business, and it stays small enough that you watch behaviour rather than crowds. It comes from Thailand and Southeast Asia and needs warm, very humid conditions all year. The semi-claustral founding means the queen has to hunt while she establishes, and the live-prey diet and high humidity together demand real experience. It suits an expert who enjoys hands-on predatory ants over big-number colonies.

A ponerine hunter at heart. The large workers take live and freshly killed insects to feed the brood, while the adults sip sugars for their own energy, so offer fresh prey regularly alongside a sugar source.

Found this rainforest predator in a test tube kept warm and very humid, then move only when the first workers cover the floor. It wants a moisture-holding nest such as ytong, 3D-printed, or an aerated acrylic setup that keeps the brood air damp, with a slightly drier arena. Upgrades stay modest, as the colony stays small. With large workers, keep a solid escape barrier of fluon (PTFE), oil, or talc-and-water on the arena. ANTonTOP formicaria and starter kits supply a matched humid nest, arena and barrier for a small, moisture-loving predatory colony.

High humidity is the headline for this rainforest species: nest humidity 70-85% and arena 60-75%, with the nest at 24-27 °C and the arena at 25-29 °C. Heat one side only so the ants can self-select their preferred zone. This is a tropical species with no hibernation, so keep it warm, humid and fed all year.

Growth is slow and deliberate in the ponerine way, with the colony staying small at up to 500 workers. You receive a single fertilised queen with workers and brood to establish the nest.

• Myopias is a genus of specialist ponerine predators, several of which are known to hunt other ants and soil arthropods.
• Founding is semi-claustral, so the queen leaves the nest to hunt while raising her first workers, unlike sealed-in seed eaters.
• Ponerines are an ancient lineage with relatively simple, small colonies and large, capable individual workers.
• The species is restricted to Southeast Asian forest, where steady warmth and high humidity are the norm.

Is Myopias sonthichaiae good for beginners?

No, it is rated Pro, with semi-claustral founding, high humidity needs and a live-prey diet that suit experienced keepers.

Does this Thai ponerine need a winter rest?

No, it is tropical and stays active year-round; never lower temperatures for a cool rest.

Does it sting or bite?

Yes, it has a sting plus a mild bite, as expected from a ponerine.

How large does the colony get?

It stays small, up to 500 workers, as a monogyne species.

How big is the queen?

The queen is 10-12 mm; workers are 9-11 mm.

How fast does it grow?

Slowly, as ponerine colonies build numbers gradually.

What do these predatory ants eat?

Mainly live and freshly killed insects such as crickets and flies, with sugars taken only occasionally; it does not eat seeds.

How do you ship live ants?

A single queen with workers and brood ships with a seasonal heat or cool pack, dispatched within 24 h with tracking for 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.
