Boltonopone picardi

Quick Summary

• Difficulty: Unknown, too little data to assess difficulty level
• Origin & Habitat: Angola, Africa, specifically the Cubango region at the southern edge and the central region between the Cubango and Cuito Rivers ^[1][2]
• Colony Type: Unknown, colony structure has not been documented. Only four worker specimens have ever been collected ^[1][2].
• Size & Growth:
  • Queen: Undocumented, no queen specimens have been described
  • Worker: 6.3-6.5mm total length ^[1][2]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown, development has not been studied (No data available on egg-to-worker development time)
• Antkeeping:
  • Temperature: Likely warm conditions based on tropical African origin. Angola has a subtropical climate with warm temperatures year-round. Start in the mid-to-high 20s Celsius and observe colony activity.
  • Humidity: Likely moderate, the species has been found in areas between rivers, suggesting they prefer neither extremely wet nor dry conditions. Provide a humidity gradient with moist substrate and some dry areas.
  • Diapause: Unlikely, Angola is tropical with minimal seasonal temperature variation. No diapause would be expected.
  • Nesting: Possibly soil-nesting based on speculation they may nest under stones. A standard test tube setup with moist substrate would be a reasonable starting point. Provide some dry areas as well.
• Behavior: Temperament is unknown but Ponerine ants are typically more defensive and may have potent stings. They are likely solitary foragers based on their tree-foraging behavior. Escape prevention should be moderate, they are medium-sized ants but standard barrier methods should work.
• Common Issues: Very limited availability, only four specimens ever collected, making this species extremely rare in the hobby, No established care protocols exist since the biology is unstudied, Unknown diet requirements, Ponerinae are typically predatory but specific prey preferences are unconfirmed, Risk of wild-caught colonies having parasites or diseases since no captive breeding has been documented

Appearance and Identification

Boltonopone picardi workers are medium-sized ants measuring 6.3-6.5mm in total length. The most distinctive feature is their nearly hairless body, the dorsal surface of the mesosoma is completely bare without erect hairs, which is their main identifying characteristic. The head is densely and roughly sculptured with very few punctulae. The body coloration is black or reddish brown, while the legs, antennae, and mandibles are red or reddish brown. Mandibles have approximately 7 teeth and are smooth. Compound eyes are relatively small. This species was formerly classified as Boltonopone picardi before being moved to the newly defined genus Boltonopone ^[1][2].

Natural History and Distribution

This species is known only from central and southern Angola in Africa, specifically from the Cubango region at the southern edge of the country and the central region between the Cubango and Cuito Rivers. Specimens have been collected from trees, suggesting they forage in arboreal habitats. It is possible they nest in soil under stones, though this has not been confirmed. The limited collection data means our understanding of their natural history is extremely incomplete, only four worker specimens exist. The region they inhabit has a subtropical climate with distinct wet and dry seasons ^[1][2].

Housing and Nesting

Since natural nesting behavior is not well documented, you will need to make educated guesses based on related Ponerine ants. A standard test tube setup works well for founding colonies. Provide moist substrate but also include some drier areas within the nest. Given their possible arboreal foraging and speculation about soil-nesting under stones, a naturalistic setup with both soil areas and climbing structures may be appropriate. Use standard escape prevention methods, they are medium-sized so typical barriers should be effective. Monitor your colony to see what humidity levels they prefer and adjust accordingly.

Feeding and Diet

Diet requirements are not documented for this species. As a Ponerine ant, they are likely predatory and would accept small live invertebrates like fruit flies, pinhead crickets, and other small insects. Ponerine ants typically have potent stings and are active hunters. Offer protein foods regularly and sugar water or honey as an energy source. Since so little is known about this specific species, observe what your colony accepts best and adjust accordingly. Start with small live prey items and sugar sources, then expand based on their preferences.

Temperature and Seasonal Care

Based on their origin in tropical Angola, these ants likely prefer warm conditions. Avoid cold temperatures as they are not adapted to cool climates. Since Angola is tropical with minimal temperature variation throughout the year, no hibernation or diapause period would be expected. Maintain stable, warm conditions year-round. A heating cable on one side of the nest can create a temperature gradient allowing the colony to self-regulate. Monitor colony activity, if workers are clustered near the heat source, increase temperature slightly, if they avoid heated areas, reduce heat.
