Meranoplus magrettii

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Sub-Saharan Africa including Sudan, Ghana, Kenya, Tanzania, Uganda, Botswana, Democratic Republic of Congo, Mozambique, South Africa, and Zimbabwe. They inhabit savannah, open woodland, and grassland habitats ^[2][3].
• Colony Type: Colony structure is unconfirmed. No species-specific literature documents queen number or colony social structure.
• Size & Growth:
  • Queen: Size data unavailable, queen measurements have not been documented in available literature
  • Worker: 2.5-3mm ^[1][2]
  • Colony: Unknown, no documented colony size. One study recorded 221 individuals in a population sample from woodland habitats ^[4].
  • Growth: Unknown, no development timing data exists for this species
  • Development: Unknown, development timing has not been studied (No species-specific data available. Temperature and nutrition likely influence development speed.)
• Antkeeping:
  • Temperature: Keep at room temperature around 22-26°C. This species comes from warm African habitats, so they tolerate temperatures in the low-to-mid 20s°C well.
  • Humidity: Keep the nest substrate consistently moist but not waterlogged. Allow the surface to dry slightly between waterings.
  • Diapause: Unknown, no specific research on winter dormancy. As an African savannah species, they likely do not require true hibernation. Monitor colony behavior and reduce feeding if they become less active during cooler months.
  • Nesting: Soil-nesting species. Provide a naturalistic setup with moist soil at least 2-3cm deep for tunneling. Y-tong nests with soil-filled chambers or plaster nests with a soil area work well. They construct nest turrets in the wild, so provide some substrate depth for natural behavior.
• Behavior: These ants are slow-moving, nocturnal foragers that stay relatively inconspicuous ^[3]. They are not aggressive and rely on their spines for defense rather than biting or stinging. Their small size means they can escape through small gaps, use fine mesh barriers. They forage at night, so provide feeding opportunities in the evening.
• Common Issues: limited availability, this African species is rarely available in the antkeeping hobby, escape prevention is critical due to their small size, use tight-fitting lids and fine mesh, no established care protocols, keepers must adapt from related species, slow growth is likely, beginners may lose patience with slow-developing colonies, wild-caught colonies may carry parasites that can cause problems in captivity

Nest Preferences and Housing

Meranoplus magrettii nests in soil in open habitats, constructing small turret-like entrances from vegetation debris ^[3]. In captivity, provide a naturalistic setup with moist soil at least 2-3cm deep to allow for tunneling. A Y-tong nest with soil-filled chambers or a plaster nest with a soil area also works well. The key is providing enough depth for the colony to dig chambers while maintaining moderate moisture. Avoid overly wet or waterlogged substrate, these are ants of relatively drier open habitats. A small water reservoir connected to the soil area helps maintain consistent moisture without flooding.

Feeding and Diet

The natural diet of M. magrettii is not well documented. Offer sugar water or honey as a constant energy source, and provide small protein sources like fruit flies, pinhead crickets, or mealworm pieces. Since they are small ants, prey items should be appropriately sized. They forage at night, so offer food in the evening hours when they are most active. Remove uneaten food after 24-48 hours to prevent mold.

Temperature and Seasonal Care

This species comes from warm African habitats spanning from Sudan to South Africa, so they prefer temperatures in the 22-28°C range. Room temperature around 22-26°C is typically suitable. Provide a gentle thermal gradient so ants can choose their preferred temperature. A small heat cable on one side of the nest can help if your room runs cool. Regarding diapause: African savannah species may reduce activity during cooler months but do not typically require prolonged cold hibernation. Monitor your colony, if they become less active in winter, reduce feeding frequency and keep them slightly cooler for a few months rather than forcing a deep hibernation they may not be adapted for. ^[2]

Behavior and Handling

These ants are described as relatively slow-moving and inconspicuous, making them peaceful colony residents ^[3]. They are nocturnal foragers, so you may not see much activity during daylight hours. Their small size and slow movement make them easy to handle, but their spines provide some defense if threatened. They are not known for aggressive swarming or painful stings. The main challenge for keepers is their small size, they can slip through surprisingly small gaps. Use fluon on test tube rims, fine mesh on outworlds, and ensure all connections are sealed.
