Tetramorium do

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Afrotropical region (Mozambique, South Africa, Tanzania, Zimbabwe, Kenya ^[1], Eritrea ^[2], Saudi Arabia ^[3], Yemen ^[4], UAE ^[5], and DRC ^[7]). Lives in open and semi‑open areas such as meadows, bushveld, and woodland, nests in the ground ^[6].
• Colony Type: Colony structure is unconfirmed. Based on patterns in related Tetramorium, they are likely monogyne (single queen), but this has not been specifically documented for this species.
• Size & Growth:
  • Queen: Unknown, no measurement data available. Inferred from related Tetramorium species, queens are likely around 6-8 mm.
  • Worker: 3.0-3.2 mm (total length) ^[6]
  • Colony: Unknown, no published colony size data. Based on related Tetramorium, colonies may reach up to several hundred workers, but this is speculative.
  • Growth: Moderate
  • Development: Estimated 6-10 weeks based on typical Tetramorium development, actual timing varies with temperature and is not confirmed for this species. (Development likely depends on temperature, warmer conditions speed up brood growth.)
• Antkeeping:
  • Temperature: As a tropical/subtropical species, keep at 22-26 °C. Avoid prolonged exposure below 18 °C. A heating cable on one side of the nest can create a useful gradient ^[6].
  • Humidity: Moderate, keep nest substrate slightly moist but not waterlogged. These ants nest in well‑drained soil in open habitats, so avoid excess moisture ^[6].
  • Diapause: No true diapause needed. They are from warm climates and can be active year‑round. A slight winter cooling (to around 18-20 °C) is optional but not required ^[6].
  • Nesting: Ground‑nesters. Suitable nest types: Y‑tong (AAC), plaster, or a naturalistic soil setup. Test tubes work for founding colonies. Provide moderate humidity and good ventilation ^[6].
• Behavior: Generally peaceful and non‑aggressive toward keepers. They have a modified stinger used for smearing venom (characteristic of the Crematogastrini tribe), but it is not painful to humans. Workers are active foragers on the ground surface during daylight. Their small size (3 mm) makes escape prevention essential, use fine mesh and seal all gaps ^[6].
• Common Issues: escape prevention is critical, their tiny 3 mm size lets them slip through very small gaps, use 0.5 mm mesh or finer, overwatering can drown the colony or cause mold, keep nest substrate moderately dry, slow founding phase, queens may take weeks or months to raise first workers, especially if kept too cool, wild‑caught colonies may carry mites or parasites that stress the colony, quarantine new stock, colonies may decline if kept below 18 °C for long periods, maintain warmth year‑round

Housing and Nest Setup

For Tetramorium do, mimic their natural ground‑nesting habitat. A Y‑tong (AAC) nest works well, the porous clay gives the slightly dry to moderately moist conditions they prefer. Plaster nests or simple test tubes are also good for founding colonies. The nest chambers should be small (fitting their 3 mm workers) to help them feel secure. Connect the nest to an outworld (foraging area) with tubing. Use a fine mesh (at least 0.5 mm) on all ventilation openings to prevent escape. A water test tube connected to the nest provides drinking water. Place sugar water and protein dishes in the outworld, not inside the nest ^[6].

Feeding and Diet

Tetramorium do is omnivorous. Offer sugar water or honey as a constant energy source, replacing it every 2-3 days to stop fermentation. For protein, give small insects like fruit flies, small mealworms, or cricket pieces 2-3 times per week. Place food on the ground in the outworld, they are ground foragers. Remove uneaten protein after 24 hours to prevent mold. Young colonies (queen only) do not need feeding, as queens use their fat reserves until first workers appear ^[6].

Temperature and Seasonal Care

Keep the nest at 22-26 °C for good brood development. A heating cable on one side creates a gradient so the ants can choose their preferred temperature. Avoid temperatures below 18 °C for long periods, as this weakens the colony. They do not need true hibernation, being from warm climates, they are active all year. You can lower the temperature to around 18-20 °C in winter if you want a rest period, but this is optional ^[6].

Colony Founding and Development

Founding behavior is unconfirmed but likely follows the typical Tetramorium pattern: a mated queen digs a small chamber, seals herself in, and raises the first workers using stored fat reserves (claustral founding). This process probably takes 6-10 weeks at optimal temperatures, though no specific data exists for T. do. The first workers (nanitics) are usually smaller than mature workers. After they emerge, the colony enters a growth phase as the queen continues laying eggs and workers take over foraging and brood care ^[6].

Behavior and Temperament

These ants are generally peaceful and easy to observe. Workers are active foragers on the ground, searching for food and carrying pieces back to the nest. They use a modified stinger to smear venom (a trait of the Crematogastrini tribe) but it is not painful to humans, making them safe to handle. They are diurnal, with most activity during daylight. The colony has a clear division of labor: the queen focuses on egg‑laying, while workers handle foraging, brood care, and nest maintenance ^[6].
