Camponotus morosus

This is an ant for evening watchers. Hailing from Chile, it is most active around dusk and into the night, so the colony’s busiest hours line up neatly with when most keepers are home. Brood develops at a measured, watchable pace, letting you follow each stage from egg to worker. Rather than a hard hibernation it takes only a light cool rest, which makes its seasonal care gentler than that of temperate species. It suits keepers who already have a feel for humidity and feeding and want something with a bit more rhythm.

A dusk-active carpenter ant with an omnivore’s range: sugars and honeydew sustain the foragers while insect prey drives brood growth. Keep a sugar source out at all times and offer insects a few times a week; it does not take seeds.

★★★ readily · ★★ moderately · ★ occasionally · ✗ not eaten

Raise the queen in a test tube and move her once the first workers carpet the floor. A moderately humid wood-nester, it does well in a moisture-holding nest such as Ytong or acrylic with a damp chamber and a drier foraging arena. Scale up in steps as the colony grows toward several thousand, since it pauses only for a light cool rest rather than a hard winter. Keep the rim sealed with fluon, a thin oil line, or talc and water. An ANTonTOP formicarium or starter kit supplies the nest, arena and barrier as one set.

Rather than a hard hibernation, this one takes a light diapause, a brief cool rest where activity dips: keep feeding through it and there is no need to drop the temperature much, just ease back a little. Target 22-26 °C in the nest and a close 22-27 °C in the arena, keeping nest humidity at 55-65% and the arena at 40-55%. Warm one side only so the ants can pick a comfortable spot along the gradient.

Brood runs at a measured pace, around 6-8 weeks (roughly 42-56 days) from egg to worker, so the colony grows steadily rather than in bursts toward a final 3,000-5,000 workers. You receive a queen together with workers and brood to grow on in your nest.

• Camponotus morosus is a South American carpenter ant native to Chile, where it forages mainly at dusk and into the night.
• Its mild winter slowdown is a diapause rather than a deep hibernation, reflecting the temperate-to-cool climate it comes from.
• Carpenter ants carve their nests into wood but feed on honeydew and insects, leaving the timber undigested.
• Workers carry the symbiotic bacterium Blochmannia, which supplies nutrients the ants cannot make and supports the colony on a carbohydrate-rich diet.

Is Camponotus morosus good for beginners?

It is rated Intermediate, so it is better once you have kept a starter colony first.

Does it need hibernation?

It takes a light diapause, a brief cool rest where it may slow down; keep feeding and you need not lower the temperature much.

Does the dusk-active Chilean carpenter ant sting or bite?

No, it has no sting and only a mild bite.

How big does a Camponotus morosus colony get?

Up to 3,000-5,000 workers.

How large is the queen?

The queen measures 14-16 mm.

How fast does it grow?

Steady. Brood takes about 6-8 weeks (~42-56 days) per generation.

What do they eat?

Sugar water or jelly plus insects such as crickets and flies.

How are the ants shipped and will they arrive alive?

You get a queen with workers and brood plus a seasonal 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.
