Tetramorium chepocha

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Borneo, Indonesia, and Malaysia – lowland tropical dipterocarp forests ^[2][1]
• Colony Type: Unconfirmed. Based on typical Tetramorium patterns, likely monogyne (single queen) colonies.
• Size & Growth:
  • Queen: Not described in literature. Based on genus patterns, estimated 6–8 mm.
  • Worker: Size data unavailable. Based on general Tetramorium morphology, probably 3–4 mm.
  • Colony: Unknown – no colony size data exists for this species.
  • Growth: Unknown – no development data exists.
  • Development: No species-specific data. Related tropical Tetramorium may take 4–8 weeks at warm temperatures, but this is unconfirmed. (All development estimates are inferred from other Tetramorium and should be treated as rough guesses.)
• Antkeeping:
  • Temperature: No confirmed requirements. As a tropical species from Borneo, likely needs warm conditions – try 24–28°C and observe.
  • Humidity: No confirmed requirements. Rainforest origin suggests high humidity – keep substrate moist but not waterlogged, and provide a moisture gradient.
  • Diapause: Unlikely. Tropical species from Borneo probably active year-round without hibernation.
  • Nesting: Ground-nesting based on collection data ^[2]. In captivity, a naturalistic setup with moist soil or a Y-tong/plaster nest with tight chambers is recommended.
• Behavior: Workers forage during daytime ^[2]. Temperament is unknown – reports from related Tetramorium suggest they are not aggressive, but this is unconfirmed. Small size (3–4 mm) means good escape prevention is essential.
• Common Issues: extremely rare in the hobby – almost impossible to obtain legally., no captive breeding or care data exists – keepers must rely on genus-level guesses., high humidity requirements are difficult to maintain evenly in artificial nests., small (3–4 mm) workers can squeeze through tiny gaps, use fine mesh (≤0.5 mm)., defense mechanism is smearing venom (typical of Crematogastrini), but irritation risk is unknown for this species.

Natural History and Distribution

Tetramorium chepocha is endemic to the Indomalaya region, known only from Borneo, Indonesia, and Malaysia ^[1]. It was originally described from Borneo by Bolton in 1976 as Tetramorium chepocha and later moved to Tetramorium in 1985 ^[1]. Workers have been collected only in ground samples from Bornean dipterocarp forests during daytime, confirming a strictly ground-dwelling, diurnal lifestyle ^[2]. No queens or males have been described, and virtually nothing else is known about its natural history.

Housing and Nest Preferences

Without specific natural history data, recommended nesting is based on typical Tetramorium ground-nesting behavior. Use a test tube setup for founding (if a queen ever becomes available). For larger colonies, a Y-tong or plaster nest with small chambers works well. Provide deep substrate or a humid nest section because the species comes from rainforest. Escape prevention is critical: workers are small (~3–4 mm) and can slip through standard mesh. Use fine nylon mesh or fluon barriers.

Feeding and Diet

No diet data exists for this species. Based on general Tetramorium feeding, offer a varied diet: small live prey (fruit flies, pinhead crickets, small mealworms) and sugar sources (honey water, sugar water). Feed protein 2–3 times per week, remove leftovers to prevent mold. They likely also accept sweet liquids like honeydew.

Temperature and Care

No confirmed temperature or humidity data. As a tropical species from lowland Borneo, keep warm (24–28°C) and humid. Use a heating cable on part of the nest to create a gradient. Maintain high humidity by keeping nest substrate moist but not waterlogged, mist the outworld regularly. Do not hibernate – provide warmth year-round.

Behavior and Temperament

Workers are known to forage on the ground during daytime ^[2]. Their temperament is undocumented. Related Tetramorium species are usually non‑aggressive, but this is unconfirmed for T. chepocha. Like all ants, they may use chemical trails to recruit nestmates. The species belongs to subfamily Myrmicinae, tribe Crematogastrini, which uses a smearing defense: they wipe venom onto enemies with a modified, flattened stinger rather than stinging. However, it is unknown whether T. chepocha actually does this – no observational data exist.
