Plagiolepis vanderkelleni

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Akagera National Park, eastern Rwanda, a tropical savanna ecosystem with warm temperatures and seasonal rainfall ^[1].
• Colony Type: You likely face single-queen colonies, as most Plagiolepis species are monogyne (single queen). Some related species form small multi-queen groups, but data for this specific ant is unconfirmed.
• Size & Growth:
  • Queen: size data unavailable, inferred from Plagiolepis genus (~2-4 mm)
  • Worker: size data unavailable, inferred from Plagiolepis genus (~2-3 mm)
  • Colony: Up to a few hundred workers based on typical Plagiolepis patterns
  • Growth: Unknown, likely moderate
  • Development: Estimated 8-12 weeks based on typical Formicinae patterns (You monitor brood development closely, as no species-specific data exists.)
• Antkeeping:
  • Temperature: Keep warm and stable, roughly low-to-mid 20s°C. A gentle heat gradient lets you regulate conditions without guessing exact numbers.
  • Humidity: Provide a humidity gradient, keep the nest substrate consistently moist but not waterlogged. Plagiolepis species typically prefer damp conditions similar to their natural habitat.
  • Diapause: Unlikely required. As a tropical species from Rwanda, they probably do not enter true hibernation. A slight cool period during winter months may be beneficial but is not confirmed.
  • Nesting: Preferred nest types likely include test tubes, Y-tong nests, or plaster nests with small chambers scaled to their tiny size. In nature, they probably nest in soil, under stones, or in decaying wood.
• Behavior: You likely encounter non-aggressive, quick-moving ants that forage in trails. Escape prevention is critical due to their very small size, they squeeze through standard barriers easily. You feed them sugar water and small protein sources.
• Common Issues: workers escaping through tiny gaps in your setup, colony collapse from improper humidity levels, development delays due to temperature fluctuations, mold growth from uneaten protein in small nests, stress from frequent colony disturbance

New Discovery in Rwanda

You manage a species that represents a new record for Rwanda ^[1]. Researchers collected it in Akagera National Park, which features savanna, woodland, and wetland habitats along the Akagera River. This discovery shows that even well-studied genera like Plagiolepis hide undocumented species in Africa. You lack direct care data for this ant. You rely on genus-level inference for all husbandry decisions.

Nest Preferences

Based on typical Plagiolepis patterns, you likely need small, enclosed spaces for this species. Test tubes with cotton water reservoirs work well for founding colonies. As the colony grows, you switch to Y-tong nests or plaster setups with narrow chambers scaled to their tiny size. You keep the nest substrate lightly moist but not saturated. A small water tube connected to the nest helps maintain humidity without flooding.

Feeding and Diet

Based on typical Plagiolepis feeding behavior, you likely offer a varied diet to this species. You provide sugar water or honey as a constant energy source. For protein, you offer small soft-bodied prey like fruit flies, pinhead crickets, or small mealworms. You feed protein two to three times per week. You remove uneaten prey within 24 to 48 hours to prevent mold issues.

Temperature and Care

You maintain temperatures between 22 and 26°C, reflecting their tropical East African origin. You place a heating cable on one side of the nest to create a temperature gradient. You place the heating on top of the nest, not underneath, to prevent excessive drying. You monitor colony behavior. You increase temperature slightly if workers cluster near the heat source. You reduce heat if they avoid heated areas. You avoid temperatures below 20°C or above 30°C for extended periods.

Behavior and Temperament

Based on genus patterns, you likely encounter quick-moving, generally non-aggressive ants that form moderate foraging trails. Their small size helps them avoid larger ant species. You note that they do not sting and pose no danger to keepers. Your primary concern is their tiny size, which makes them expert escape artists. You use fine mesh and seal all lid seams. You keep them for observing small, active ant species.
