Pogonomyrmex badius

Pogonomyrmex badius is a intermediate pogonomyrmex from North America (Southeast). Two-toned: red head and mesosoma with darker gaster; majors with broad heads. Florida’s iconic red harvester ant — large, polymorphic, with a notable sting and classic granary biology. Pogonomyrmex — North American red harvester ants with potent stings and long-lived multi-decade queens.

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. Provide a sand-clay nest with deep chambers — harvester ants excavate and store seeds.

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: high-quality dry seed mix (poppy, sesame, fennel, dandelion, niger) offered ad libitum from a small dish. Refresh weekly.

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.

No hibernation needed. Keep this colony at stable room temperature year-round (around 22–26 °C); it stays active through winter without a cold rest period.

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 best for keepers who already maintained at least one founded colony. The care needs are not extreme, but the temperament or environmental requirements need attention. Read the care information and contact us with questions before ordering.

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 Pierre-André Latreille in 1802 from Florida.
• Ranges across the southeastern United States from North Carolina to Florida and west to Texas.
• True harvester — workers gather seeds and store them in granary chambers underground.
• Has a notable painful sting — recommended for intermediate keepers, not absolute beginners.
• Polymorphic workers — small minors and larger majors with broad heads.

How big can the colony grow?

monogyne, claustral founding, mature colonies 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 can bite or sting defensively when the formicarium is opened. Supervise children and keep curious pets away from the setup.

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.

Can I skip hibernation?

Yes. This species does not require hibernation — keep it warm and active all year, with no cold rest to schedule.

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.
