Pachycondyla crassinoda

This is a predatory ponerine through and through: heavy, powerful workers that hunt live prey rather than tend aphids or hoard seeds. The trade-off that makes it appealing is scale, it stays a small colony, so it fits a compact setup yet never feels crowded, and because the individual ants are so large you watch them one by one rather than as a swarm. It founds on a single queen and moves with a slow, deliberate gait that suits close observation. The semi-claustral founding and high humidity needs make it a Pro step up from typical beginner ants, but for a heavyweight tropical hunter it delivers.

A powerful ponerine predator that hunts live prey individually rather than swarming it, carrying victims back whole. Insect prey drives the brood, while the big workers take sugars now and then for their own energy.

Founding is semi-claustral, so the queen needs food from the start: begin in a test tube setup or a compact ANTonTOP starter kit with feeding access. This large ponerine comes from damp Guianan forest, so move it into a moisture-retaining, hydratable formicarium with deep chambers to suit a big-bodied ant. Add a roomy hunting arena and upgrade nest size as the colony nears its 500-worker ceiling. Run an escape barrier on the arena: fluon (PTFE) on smooth walls, or oil where PTFE will not hold. ANTonTOP formicaria and starter kits supply the damp nest, arena and barrier together.

A moisture-loving tropical ant from the forests of French Guiana. Keep the nest at 24-27 °C and the arena at 24-28 °C, with nest humidity 70-85% and arena humidity 60-75%. Build a gentle gradient with a heat mat on one side and keep a reliably damp zone in the nest. It is tropical with no hibernation: keep it warm, humid and fed all year.

Like most ponerines this colony grows slowly and stays modest, topping out around 500 workers, so expect a calm, watchable pace rather than a population boom. The large workers make individuals easy to track. You receive a queen with workers and brood, ready for a humid nest with feeding access from the start.

• This is one of the heaviest-bodied ponerines in the hobby, with workers of 18-20 mm running nearly as large as the queen.
• Ponerines are considered an anatomically primitive lineage of ants, retaining traits closer to their wasp ancestors than most modern groups.
• Rather than recruiting in mass trails, these ants tend to hunt as lone foragers, subduing prey one on one.
• A founding queen of this genus can live for well over a decade, far longer than most colony-mate workers.

Is Pachycondyla crassinoda good for beginners?

No, it is a Pro-level ponerine with semi-claustral founding and high humidity needs, better as a second or third colony.

Does Pachycondyla crassinoda need a winter rest?

No. It is tropical and active all year; keep it warm, humid and fed.

Does this ponerine sting or bite?

Yes, it has a sting plus a mild bite, so avoid handling.

How big does this colony of big ants get?

Up to 500 workers, small and manageable.

How big is the queen?

The queen is 21-23 mm and workers are 18-20 mm, so the whole colony runs large.

How fast does it grow?

Slowly; ponerines build small colonies at a measured pace.

What does this ponerine feed on?

Mainly live insects such as crickets and flies, with sugar water or jelly as a supplement.

How is it shipped and will it arrive alive?

You get a queen with workers and brood plus a heat or cool pack, dispatched within 24 h with tracking to keep transit fast and safe.

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.
