Tetraponera perlonga

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to Madagascar, found in tropical dry forests such as Kirindy Forest in the west and Vohibasia forest in the south ^[2][3]. They are arboreal, nesting in hollow plant stems and twigs ^[3]. Madagascar has a warm climate year-round with distinct wet and dry seasons.
• Colony Type: Colony structure is not well documented. Based on related Tetraponera species, they likely have moderate-sized colonies with a single queen (monogyne), but this is unconfirmed.
• Size & Growth:
  • Queen: ~7-8 mm – inferred from Tetraponera genus patterns (no direct measurements available)
  • Worker: ~4-6 mm – inferred from Tetraponera allaborans group patterns (no direct measurements available)
  • Colony: Up to several hundred workers at maturity – estimated from related Tetraponera species
  • Growth: Moderate – estimated based on related species
  • Development: Estimated 6-10 weeks at optimal temperature (based on related Pseudomyrmecinae, not confirmed for this species) (Specific development data for *T. perlonga* is lacking. Expect similar timelines to other tropical Tetraponera species.)
• Antkeeping:
  • Temperature: Keep around 24-28°C to mimic tropical conditions. Specific temperature data is unavailable, but this range matches Madagascar's lowland forests where the species occurs ^[2].
  • Humidity: Moderate to high humidity (substrate slightly moist but not waterlogged). As an arboreal species from humid forests, they need consistent moisture but good ventilation to prevent mold. Mist the outworld and provide a water source like a test tube with a cotton plug.
  • Diapause: No true diapause required – Madagascar is tropical with little seasonal temperature change. You can lower the temperature slightly to 22-24°C during the winter months if you want to simulate natural seasonal patterns, but it's not necessary.
  • Nesting: Arboreal setup is essential. Provide hollow twigs, cork bark, or test tubes positioned horizontally to mimic stem cavities. Avoid standard soil formicariums. A naturalistic terrarium with cork branches and climbing structures works well. Ensure nest chambers are narrow (3-5 mm wide) to simulate natural stems.
• Behavior: Active and alert ants with good vision – they will explore the outworld and investigate new items quickly. They are not aggressive toward keepers but will defend their nest if disturbed. Escape prevention is important as they are small and agile. They forage actively and will hunt small prey.
• Common Issues: arboreal setup is required – they won't thrive in standard ground nests, escape risk is high due to their small size and agility, limited care information is available, so you may need to experiment, humidity must be balanced – too dry causes stress, too wet promotes mold, wild-caught colonies may carry parasites or suffer from collection stress

Housing and Nest Setup

Tetraponera perlonga requires an arboreal setup since they nest in hollow stems and twigs in nature ^[3]. The best options include cork bark nests, custom nests with narrow vertical chambers, or test tubes positioned horizontally to mimic stem cavities. You can also create a naturalistic terrarium with cork bark pieces, artificial vines, or small twigs. Avoid standard flat formicariums – these ants prefer to be off the ground. If you use a Y-tong (AAC) nest, add climbing structures in the outworld. Keep chambers narrow, around 3-5 mm, to match their natural habitat.

Temperature and Heating

Keep temperatures between 24-28°C for best growth and brood development. This species comes from tropical Madagascar, which is warm year-round ^[2]. Room temperature may not be enough, so use a small heating cable or mat on one side to create a warm zone. Place heating on the top or side of the nest, not underneath, to avoid drying out the nest too fast. A temperature gradient lets ants choose their preferred spot. In winter, a slight drop to 22-24°C is fine, but avoid going below 20°C.

Feeding and Diet

Like other Pseudomyrmecinae ants, T. perlonga is predatory. Offer small live insects such as fruit flies, pinhead crickets, or small mealworms. They are active hunters and will chase prey. They also accept sugar sources like diluted honey or sugar water occasionally. Provide fresh water at all times. Feed every 2-3 days and remove uneaten food after 24 hours to prevent mold. A varied diet supports healthy colony growth. ^[1]

Humidity and Water

Keep humidity moderate to high – the nest substrate should be slightly damp but not wet. As an arboreal species from humid forests, they need consistent moisture but also good airflow ^[3]. Mist the outworld and offer a water source like a test tube with a cotton plug. Poor humidity causes stress and brood loss, but too much moisture without ventilation leads to mold. Balance damp nest areas with a drier outworld.

Behavior and Colony Dynamics

These ants are fast and alert with excellent vision – common in arboreal Pseudomyrmecinae. Workers patrol their territory and investigate new objects. They are not aggressive to humans but will defend the nest if threatened. Colonies grow at a moderate pace. The queen lays eggs continuously once established. Workers divide labor between brood care and foraging. The colony expands over months to years, eventually reaching several hundred workers. ^[1]
