Camponotus terebrans

This is a proper carpenter ant with continuous polymorphism, so a mature nest runs the full spread from small minors up to big-headed majors, and watching that range fill in is a large part of the appeal. The colour is variable and often striking: the head runs red-brown to black, the mesosoma and node sit somewhere between yellow and brown, the gaster is darker, and the legs stay a lighter yellow-brown. Founding is claustral, so the queen raises her first workers sealed away on her own reserves and asks for nothing during that phase. The colony can grow large over time, which keeps a setup interesting for years. Activity is mainly nocturnal, so expect the arena to come alive in the evening. It rates Intermediate: forgiving on food and founding, but it does want the right dry setup and a genuine winter rest, so it suits a keeper past their first colony.

A straightforward omnivore. Adults and the queen run on sugars, so keep a carbohydrate source available at all times, and the growing brood needs regular insect protein. Offer a constant sugar or nectar feeder plus live or freshly thawed insects a few times a week.

Start the founding queen in a water test tube and leave her undisturbed until the first workers are on their feet, since she founds claustral and needs nothing but calm and dark. As the colony grows, move it into a gypsum or aerated-concrete nest with roomy chambers to suit a large-bodied ant, paired with a spacious outworld for foraging. This is a dry-soil specialist, so run the nest on the dry side with only a small moist zone rather than a wet setup. Seal every open rim with fluon (PTFE), oil, or a talc-and-water mix and fit a tight, fine-mesh lid, because carpenter ants climb and probe for gaps. ANTonTOP formicaria and starter kits supply a scaled nest, arena and barrier in one ready set.

Keep the active season at 22-26 °C. Humidity should stay low: this is a sandy-soil specialist that wants a dry nest with just a small moist corner so the colony can pick its own spot. Heat one side of the nest only and leave a cooler side, rather than holding the whole setup at one temperature. It comes from temperate southern Australia with a real winter, so it needs a genuine cool rest: drop it to about 15-18 °C for two to three months in the colder part of the year. That winter diapause supports queen longevity and a natural colony rhythm.

Because founding is claustral, the queen gets the first workers going on her own without help, and once workers are out the pace picks up. Given warmth, steady food and time, this species can build into a very large colony, so the interest grows year on year as the polymorphic worker range fills in. What you receive is a laying queen with a group of workers and brood, a complete colony ready to move into its first nest and grow on.

• Camponotus terebrans was described by Benjamin Lowne in 1865, originally as Formica terebrans; the name replaced the preoccupied Formica testaceipes.
• It is one of the most common ants in southern-Australian sandy soils and a fast pioneer of disturbed or bare sand.
• It acts as an ecosystem engineer and strong competitor, able to displace Iridomyrmex and take over Myrmecia nests.
• Colonies build long, shallow subsurface “highways”, semicircular soil mounds over tunnels that can run more than 50 m long.
• Only the smallest minor workers forage far from the nest.

Is Camponotus terebrans suitable for beginners?

It rates Intermediate. Founding is claustral and feeding is easy, but it wants a dry setup and a real winter rest, so it suits a keeper past their very first colony rather than a complete newcomer.

Does Camponotus terebrans need a winter rest?

Yes. It comes from temperate southern Australia with a genuine winter, so give it a cool diapause at about 15-18 °C for two to three months in the colder part of the year.

Does it sting or bite?

It has no sting. Like other carpenter ants it defends itself by biting and spraying formic acid, which is harmless in normal keeping.

How big do the workers get?

Workers are polymorphic. Minors run about 8 mm, while majors reach roughly 10-12 mm with an enlarged head. The queen is around 12 mm.

How large does the colony get?

It can become very large over time. There is no fixed cap, so given warmth and steady feeding the nest keeps growing for years.

What should I feed it?

A constant sugar or nectar source plus live or freshly thawed insects such as crickets, roaches and houseflies. It is an omnivore, not a seed eater, so soft and hard seeds are ignored.

Why is the arena quiet during the day?

This species is mainly nocturnal, so most foraging happens in the evening and at night. That is normal, not a sign of a problem.

Will my colony arrive alive?

Yes. You receive a queen with workers and brood, shipped with a heat or cool pack to suit the season and dispatched with tracking, under our live-arrival guarantee.

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, because carpenter ants are persistent climbers.

Keeping reminders. Always offer fresh water and keep a carbohydrate source available at all times. Give live or thawed protein a few times a week, and remove uneaten prey within 24 hours before it moulds. Keep the formicarium out of direct sunlight and away from constant vibration, which stresses the colony.

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. Moving a small colony into a large nest too soon invites mould, mites and stress. Keep the colony in its test tube on the arena and open up the next chambers only once it fills its current 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.
