Crematogaster scutellaris

Crematogaster scutellaris is a beginner crematogaster from Mediterranean Europe and North Africa. Vivid red head and mesosoma with a contrasting matt black gaster. The classic Mediterranean acrobat ant — red front, black gaster, and the genus’s textbook threat posture. Crematogaster — acrobat ants that lift their heart-shaped gaster over the body when alarmed.

Start the founded queen in a sealed glass test tube setup until the colony reaches 15–20 workers. Then move to a small-to-medium formicarium of acrylic, ytong or plaster with a connected outworld. Add red filter film or a dark cover to give the colony a sense of nest darkness.

Keep the nest at 22–28 °C during the active season. Humidity in the nest chambers should sit around 40–65 %, with one wetter zone the colony can choose. Avoid direct sun and heavy hot spots — gentle ambient warmth from a low-wattage heat mat on one wall is ideal.

Sugar source: sugar source (honey water, jelly) 3 times per week. They love hemipteran honeydew. Small fresh-frozen insects 1 time per week. Hydrate constantly.

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.

Winter rest is essential for this species. Winter rest at 5–10 °C for 4 months mandatory. Drop temperature gradually over 2 weeks, keep the colony in a cool, dark, draft-free place, check humidity weekly, and resume normal feeding when temperatures rise again in spring. Skipping hibernation shortens queen life and disrupts brood cycles.

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.

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 Guillaume-Antoine Olivier in 1792 from Italy — one of the earliest formally named Crematogaster.
• Ranges across the Mediterranean basin from Iberia through France, Italy, the Balkans, and into North Africa.
• Famous for its association with cork oak (Quercus suber) — nests in bark crevices and exploits the bark for honeydew sources.
• The species name (scutellaris) refers to the small shield (scutellum) visible on the dorsum of the mesosoma.
• One of the most popular Crematogaster in the European hobby — vivid colour and fast growth in captive care.

How big can the colony grow?

monogyne, claustral founding, fast-growing colonies of several 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 photos.

Can I skip hibernation?

No. Hibernation is essential for this temperate species — queens need the cold rest to maintain long-term fertility and brood cycles.

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.
