Camponotus saxatilis

Camponotus saxatilis is a large beginner Camponotus from Eastern Europe and Central Asia. Dark brown to nearly black with a faint silvery pubescence on the gaster. Colonies are monogyne, claustral founding, mature colonies a few thousand workers and diurnal forager on rocky outcrops and dry steppe. A great pick for keepers who appreciate classic carpenter-ant biology – slow steady growth, intelligent foragers and visible polymorphism between minor and major workers.

Start the founded queen in a sealed glass test tube setup until the colony reaches 15–20 workers. Then move to a medium-to-large formicarium of acrylic, ytong or plaster with a connected outworld for foraging. A footprint of around 20 × 15 cm works well for the first 1–2 years. Add red filter film or a dark cover to give the colony a sense of nest darkness – Camponotus are calmer when the chambers stay shaded.

Keep the nest at 22–28 °C during the active season. Humidity in the nest chambers should sit around 50–65 %, with one wetter zone the colony can choose. Avoid direct sun and avoid heating from a single hot spot – gentle ambient warmth from a low-wattage heat mat on one wall is ideal.

• Sugar source: honey water, sugar water (1:3) or commercial ant jelly – 2–3 times per week. Camponotus love sugars.
• Protein: fresh frozen and thawed insects – crickets, mealworms, fruit flies, cockroaches – 1–2 times per week. Increase frequency when brood is present.
• Variety helps: rotate prey species so the colony gets a balanced amino-acid profile; never feed only mealworms.
• Hydration: always offer plain water on a separate cotton, never let the test tube reservoir run dry.
• Hygiene: remove leftover insects after 24 hours to prevent mould and mites.

This species needs a genuine winter rest. Cool the colony for the cold period shown in the specifications above, then warm it gradually in spring. Keeping it at room temperature all year shortens the queen’s life and stops the brood cycle, so the winter rest must not be skipped.

• Apply PTFE escape barrier on the top inner edge of the outworld – reapply every few months.
• Use a tight lid with fine mesh; check it after every cleaning.
• Inspect the formicarium silicone joints and tubing connectors monthly.
• Keep the outworld dry on the inside edge where PTFE is applied – wet PTFE loses grip.

• Never disturb the queen during founding. Keep her in the dark, in a test tube, with minimal vibration.
• Move the colony to a formicarium only when there are 15–20 workers and the test tube is genuinely full.
• Always offer water on a separate cotton outside the food.
• Quarantine any new insect feed for 24 hours before offering it to the colony.
• Avoid synthetic fragrances, smoke and aerosols in the room with the colony – Camponotus are very sensitive.

This species is a good fit for first-time keepers. Even so, an ant colony is a living organism – your responsibility starts the moment it arrives. Read the care information here and in our care guides before placing the order, and contact us if anything is unclear.

Your colony ships in a sealed glass test tube with a cotton water reservoir and a cotton plug – the same setup we use ourselves. It is packed in an insulated, padded shipping box. We hand-pick every colony, count workers and inspect the queen on the day of dispatch.

• Described by Mikhail Ruzsky in 1895 from Crimea – the species name (saxatilis = of rocks) describes its preferred rocky habitat.
• Ranges across the Caucasus, southern Russia, Ukraine, and into Central Asia and northern Iran.
• Strongly associated with rocky outcrops, dry-stone walls, and scree slopes – rarely found in forested habitat.
• Highly cold-tolerant – colonies overwinter in nest chambers under deeply chilled stones with no problems.
• Often associated with feral grape and almond orchards in the southern parts of its range.

How big can the colony grow?
Monogyne, claustral founding, mature colonies a few thousand workers. Growth is steady but not explosive – give the colony 1–2 years to reach a few hundred workers.

Is this species safe around children and pets?
Workers do not sting and rarely bite if the formicarium is intact. As with any live insect, supervise children around the setup and keep it out of reach of curious pets.

Will the colony arrive alive?
Yes. We use insulated, padded boxes and ship only on weekdays when forecasted weather along the route is safe. If anything goes wrong in transit, contact us within 24 hours of delivery with an unboxing video.

Does this species need hibernation?
Yes – this is a temperate species that needs a real winter rest. Give it the cold period shown in the specifications; skipping it harms the queen’s fertility and brood cycle.

Can I see this species in your video shorts?
We post regular video shorts of feeding sessions, brood close-ups and worker behaviour on our social channels – search “ANTonTOP” on YouTube, Instagram and TikTok.
