Terataner bottegoi

Terataner bottegoi

Terataner bottegoi is a small to medium-sized ant species native to East Africa, found in Kenya, Somalia, and Tanzania. Workers measure 4.8-6.0mm and are entirely black with brownish appendages. They have distinctive raised frontal carinae (ridge-like structures) on their head and feature strongly marginated pronotum with sharp angular corners. The dorsal surfaces are covered in conspicuous white to silvery hairs, giving them a somewhat fuzzy appearance ^[1][2].

This species is notable for having ergatoid queens, wingless queens that develop from workers rather than the typical winged reproductive forms. Colonies are monogynous, meaning they maintain a single queen. In the wild, they nest in dead aerial twigs and small plant cavities, typically in dry forest habitats along the Kenyan coast. They are predators, feeding on other arthropods including ants and termites ^[3][1].

Quick Summary

• Difficulty: Medium
• Origin & Habitat: East Africa (Kenya, Somalia, Tanzania) in dry forest habitats. Nests in dead aerial twigs and preformed plant cavities like branches or twigs on the ground or in bushes ^[3][1].
• Colony Type: Monogynous colonies with a single ergatoid (wingless) queen. Ergatoid queens serve as replacement reproductives if the primary queen dies ^[1][2].
  • Colony: Monogyne
• Size & Growth:
  • Queen: Ergatoid queens, size not specifically documented but similar to workers ^[2]
  • Worker: 4.8-6.0mm ^[1]
  • Colony: Colony size not documented in available literature
  • Growth: Moderate, typical for Myrmicinae
  • Development: Estimated 6-10 weeks based on related Myrmicinae species at optimal temperature (Development time inferred from genus-level data, no species-specific studies available)
• Antkeeping:
  • Temperature: Keep at 22-26°C. They are an East African species adapted to warm conditions. A gentle temperature gradient allows workers to self-regulate ^[3].
  • Humidity: Moderate humidity around 50-70%. These are dry forest ants, so avoid overly damp conditions. Provide a water tube but ensure the nest area stays relatively dry.
  • Diapause: Likely a short diapause period during the cooler dry season. Reduce temperature to 15-18°C for 2-3 months if colony shows reduced activity.
  • Nesting: Provide nests in dead twigs, small cork bark sections, or acrylic nests with narrow chambers. They prefer tight spaces similar to their natural twig nests. Y-tong or plaster nests with small chambers work well.
• Behavior: This is a predatory ant species that actively hunts other arthropods including ants and termites. Workers are moderately aggressive and will defend the colony vigorously. They are not known for being particularly escape-prone, but standard barrier precautions should still be taken. Workers are active foragers that search for prey rather than tending aphids. They are primarily nocturnal or crepuscular in their foraging patterns.
• Common Issues: colonies may struggle if prey is not available regularly, they need protein-rich food, dry forest habitat means they are sensitive to excessive moisture and mold, ergatoid queens are fragile and may be rejected if disturbed during introduction, slow colony growth compared to more common ant species, limited availability in the antkeeping hobby makes this a challenging species to acquire

Housing and Nest Preferences

Terataner bottegoi naturally nests in dead aerial twigs and small plant cavities. In captivity, you can simulate this by providing nests with tight, narrow chambers. Y-tong (AAC) nests work well, as do small cork bark sections or plaster nests designed for small Myrmicinae. The key is giving them appropriately sized spaces, chambers should be snug for the workers, not spacious. Avoid large open areas in the nest as they prefer the tight confines of their natural twig homes. An outworld area of moderate size with substrate for foraging completes the setup. Use a test tube connected to the formicarium for water access ^[3][1].

Feeding and Diet

These ants are predators by nature, feeding primarily on other arthropods, their larvae, and often other ants or termites ^[3]. In captivity, offer a varied protein diet including small live insects like fruit flies, pinhead crickets, and mealworms. They will also accept dead insects and may take protein jelly or frozen insects. Sugar sources like honey water or sugar water are typically accepted for energy, though protein should make up the majority of their diet. Feed every 2-3 days, removing uneaten prey after 24 hours to prevent mold. A constant sugar water supply is recommended. Unlike some ants, they do not tend aphids or collect honeydew as a primary food source.

Temperature and Seasonal Care

As an East African species from Kenya, Somalia, and Tanzania, Terataner bottegoi prefers warm conditions. Maintain temperatures between 22-26°C for optimal colony health and brood development. A slight temperature gradient in the outworld allows workers to regulate their body temperature by moving between warmer and cooler areas. During the cooler months or if the colony shows reduced activity, you may simulate a mild diapause by lowering temperatures to 15-18°C for 2-3 months. This mimics their natural seasonal cycle in the dry forests of East Africa. Avoid temperatures below 15°C as this can be harmful. Room temperature within their preferred range is acceptable, otherwise use a heating cable on one side of the nest ^[3].

Colony Structure and Ergatoid Queens

This species is unusual in that colonies are monogynous with a single ergatoid queen rather than the typical winged queen. Ergatoid queens are wingless females that develop from worker larvae and can serve as replacement reproductives if the primary queen dies or becomes ineffective. This means the colony has built-in succession planning, if something happens to the queen, an ergatoid can take over egg-laying duties. When establishing a colony from a wild-caught queen, you may receive an ergatoid rather than a winged queen. The colony will typically contain one ergatoid queen and workers of various sizes ^[1][2].

Behavior and Temperament

Terataner bottegoi workers are active predators with moderate aggression when defending their colony. They forage actively, searching for prey rather than waiting for food to come to them. Workers communicate through chemical trails and will recruit nestmates to large prey items. They are not typically skittish but will bite if threatened. Their small size (under 6mm) means they can squeeze through small gaps, so ensure your formicarium has tight-fitting connections and use fluon or other barriers on the outworld. They are primarily nocturnal or crepuscular, so you may see more activity during evening hours. Their predatory nature makes them interesting to watch as they hunt and subdue prey.
