• Difficulty: Intermediate
• Founding: Fully claustral
• Diet: Sugars & nectar + insect protein
• Temperature: ~78–84°F warm gradient

• Signature move: Flags the heart-shaped gaster overhead
• Heads up: Tiny workers — escape artists

Founding the Colony

Crematogaster founds fully claustrally — keep the queen in a dark test tube with a water reservoir and leave her undisturbed until her first workers appear. No feeding is needed during this stage.

Feeding

Acrobat ants are sugar-lovers. Keep nectar or sugar water available at all times — it drives their energy and foraging — and add insect protein (fruit flies, small feeders) regularly to push brood growth.

Heating & Setup

A warm gradient around 78–84°F keeps them active and growing. The big challenge with this species is containment: the minor workers are tiny and slip through the smallest gaps. Use a well-sealed setup, keep barriers (fluon/oil) fresh, and watch tubing connections.

Growth & What to Expect

Fast and lively. Small workers and quick brood cycles mean numbers climb rapidly once the colony establishes. Expect constant activity, busy trails, and that signature acrobatic posture whenever they're disturbed.

A Note on Defense

Crematogaster carry a mild sting they use to dab a chemical defense rather than jab — harmless to most keepers. Their real “defense” against you is their size: stay on top of containment and you'll have a trouble-free, fascinating colony.
