Tetramorium ericae

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Afrotropical region – native to Zimbabwe, recently recorded in Rwanda's Akagera National Park ^[2] and Nigeria ^[3]. Likely inhabits ground-level nesting sites in savanna or forest edge environments typical of Tetramorium ^[1].
• Colony Type: Unconfirmed – likely monogyne (single queen) based on genus patterns.
• Size & Growth:
  • Queen: 5–7 mm (estimated, based on Tetramorium genus range)
  • Worker: 2–4 mm (estimated, based on Tetramorium genus range)
  • Colony: Up to several hundred workers (estimated)
  • Growth: Moderate (estimated)
  • Development: 6–10 weeks (estimated, based on related species) (Direct development data unavailable.)
• Antkeeping:
  • Temperature: 24–28°C – inferred from tropical origin ^[1]. Provide a thermal gradient with a heating cable.
  • Humidity: Moderate – keep substrate slightly moist but allow some drying, provide a shallow water reservoir.
  • Diapause: None required – tropical species, maintain warmth year-round.
  • Nesting: Y-tong (AAC) or plaster nests work well. Test tubes for founding. Ensure fine mesh or fluon barriers for escape prevention.
• Behavior: Generally peaceful but uses a modified stinger to smear venom when threatened (typical of tribe Crematogastrini). Workers are active foragers. Small size demands careful escape prevention.
• Common Issues: identification is difficult – confirmed records limited to southern and eastern Africa ^[3]., limited species-specific data forces reliance on genus-level care guidelines., small workers can escape through standard mesh – use fine barriers., requires consistent warmth, cannot tolerate cool temperatures., colony growth may be slow compared to more commonly kept species.

Temperature and Heating

Tetramorium ericae comes from tropical Africa and needs warmth ^[1]. Keep the nest at 24–28°C for best growth. Place a heating cable on top of the nest (not underneath) to create a gentle temperature gradient. If your room is naturally warm, you may not need extra heat – watch activity levels to judge.

Feeding and Diet

Like most Tetramorium, this species is omnivorous. Offer small insects (fruit flies, small crickets, mealworms) for protein twice a week, plus sugar water or honey water in moderation. Some keepers report seed acceptance. Remove uneaten food after 24 hours to prevent mold. Provide fresh water in a cotton-plugged tube.

Nesting and Housing

Tetramorium ericae likely nests in soil or under rocks in the wild. For captive colonies, Y-tong (AAC) or plaster nests are good choices – they hold humidity well. Test tubes work for founding. Because workers are only 2–4 mm, seal all gaps, use fine mesh or fluon on outworld edges to prevent escape.

Colony Founding

Founding behaviour has not been documented for this species, but based on general Tetramorium patterns the queen probably founds claustrally – sealing herself in a chamber and raising the first brood on stored reserves. Keep the founding setup dark and undisturbed. First workers (nanitics) will be smaller than mature ones.

Behavior and Temperament

Tetramorium ericae is not aggressive. Workers are active foragers that form trails to food. They have a modified, spatulate stinger used to smear venom onto enemies – a characteristic of the tribe Crematogastrini. Bites are harmless to humans. Colonies are probably single-queen, but this hasn't been confirmed.
