Camponotus saxatilis

This is a hardy temperate carpenter ant from Crimea, and the seasonal cycle is the heart of keeping it. As the colony builds over successive years you watch real size variation appear, the larger majors emerging beside the smaller workers. It is rated Intermediate chiefly for its mandatory winter rest, which asks for a fridge or cool spot rather than constant warmth, so it suits a keeper happy to run an annual dormancy. On diet and handling it is forgiving, but that cool period is non-negotiable. A satisfying long-lived European project for someone who wants more than a year-round tropical.

This temperate carpenter ant takes sugary liquids to power the workers and insect protein to grow the brood through the active season. Feeding tapers right down over its winter rest, when the colony is dormant and asks for little.

Raise the founding queen in a test tube and move her once the colony fills its space, roughly thirty to fifty workers. A moisture-gradient nest in Ytong, aerated concrete, or acrylic suits it, dry through the chambers with one damp corner, plus an outworld. This hibernating species needs a stable nest before its mandatory winter rest at five to ten degrees. Line the rim with fluon (PTFE), oil, or talc and water, as these ants climb. ANTonTOP starter kits bundle the nest, arena, and barrier with room to grow.

Keep the nest at 20-24 °C and the arena at 22-28 °C, with nest humidity 50-70% and the arena drier at 30-50%. Heat one side with a cable or mat so the ants can choose their warmth along a gradient. The winter rest is the non-negotiable part: a cool, dark dormancy at 5-10 °C for 4 months every year, with feeding cut to a trickle through that stretch.

Growth is slow to moderate, with a patient founding phase that speeds up once the first workers harden, and the yearly cool rest sets the overall pace. Across several years it works toward as many as 10,000 workers. You receive a healthy queen with her workers and brood to begin.

• saxatilis means ‘living among rocks’, pointing to the stony, sun-warmed habitats this Palaearctic ant favours.
• It needs a proper cold winter; the annual dormancy is wired into its biology, not just a care preference.
• Carpenter ants hollow out wood and cavities for their nests but do not eat the material, unlike termites.
• The genus has no sting and defends itself with formic acid, a defining feature of the Formicinae.

Is Camponotus saxatilis good for beginners?

It is rated Intermediate, suitable once you can give it a proper 4-month winter rest at 5-10 °C.

Does the Crimean carpenter ant need hibernation?

Yes, a cool winter rest at 5-10 °C for 4 months is mandatory every year.

Does Camponotus saxatilis sting or bite?

No, there is no sting; workers only give a mild bite.

How big can the colony get?

Up to 10,000 workers over time.

How large is the queen?

The queen measures 15-18 mm, with workers at 6-9 mm and majors 10-12 mm.

How fast does it grow?

Slow to moderate; founding is patient, then growth accelerates as workers mature.

What does it eat?

Sugar water or jelly for energy plus insects like crickets and flies for protein.

Will it arrive alive?

Yes, it ships as a queen with workers and brood, with a heat or cool pack, dispatched within 24 h 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.
