Pheidole makirovana

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Makirovana Forest, Antsiranana region, northern Madagascar. Found in transitional humid forest, rainforest, and montane rainforest at 450-1200m elevation. Nests in rotten logs and rotten twigs on the ground ^[1].
• Colony Type: Colony structure is unconfirmed for this species. No specific data on queen number or social structure.
• Size & Growth:
  • Queen: Size data unavailable ^[1]
  • Worker: Size data unavailable for full body length ^[1]
  • Colony: Unknown ^[1]
  • Growth: Unknown
  • Development: Estimated 6-8 weeks based on typical Pheidole development patterns at optimal temperature (Direct development data unavailable. Estimates based on genus-level patterns for Pheidole in Madagascar.)
• Antkeeping:
  • Temperature: Temperature needs are unclear, start around 22-25°C and observe, based on natural habitat elevation ^[1]
  • Humidity: Keep nest substrate consistently moist but not waterlogged, as they nest in humid forests ^[1]
  • Diapause: Unknown, no research on seasonal behavior ^[1]
  • Nesting: Provide rotting wood pieces, cork, or naturalistic setup with damp substrate. They naturally nest in rotten logs and twigs ^[1]
• Behavior: Pheidole makirovana has major workers with a functional sting, which can deliver a mild sting if provoked. Workers are active foragers, with minors handling most foraging duties. Minor workers are very small, so escape prevention is important. They are omnivorous ^[1].
• Common Issues: high humidity maintenance is critical, drying out causes colony collapse, newly described species means limited captive breeding information, wild-caught colonies may struggle, rotten wood nesting preference requires specific setup, standard test tubes alone may not be ideal, small minor workers may have difficulty with larger prey items, colony size unknown so growth expectations are uncertain

Housing and Nest Setup

Pheidole makirovana naturally nests in rotten logs and rotten twigs on the forest floor, indicating a preference for damp, decaying wood. In captivity, provide a naturalistic setup with pieces of cork, rotting wood, or a well-moistened plaster or Y-tong formicarium. The nest material should be able to hold moisture without becoming waterlogged. A hybrid approach works well: a test tube setup for the founding chamber connected to a naturalistic area with damp substrate. Ensure the outworld provides easy access to food while the nest area maintains high humidity. Because minor workers are very small, ensure all connections between nest areas are secure and free of gaps that could allow escapes ^[1].

Feeding and Diet

Pheidole ants are omnivorous and will accept a varied diet. Offer protein sources such as small insects (fruit flies, pinhead crickets, mealworms), and sugar sources including honey water or sugar water. In their natural rainforest habitat, they likely forage for small arthropods. Feed minors small prey items they can handle, and allow majors to process larger pieces. Provide a constant sugar water source and protein 2-3 times per week. Remove uneaten prey after 24 hours to prevent mold.

Temperature and Humidity

This species comes from mid-elevation rainforest in northern Madagascar (450-1200m), so they prefer warm but not extreme temperatures. Keep the nest at roughly 22-25°C with a slight gradient if possible. Avoid temperatures above 30°C as this can stress the colony. Humidity is critical, maintain consistently moist substrate without waterlogging. Use a water reservoir or mist regularly to maintain moisture ^[1].

Colony Development

As a recently described species (2020), there is limited captive breeding information. Queens likely seal themselves in a chamber to found colonies, but founding behavior is unconfirmed. Expect the first nanitic workers to appear after 6-8 weeks at optimal temperature, though this is estimated based on typical Pheidole development. Initial colony growth will be slow as the queen focuses on producing workers. Once the first majors appear, colony development typically accelerates.

Behavior and Temperament

Pheidole makirovana exhibits the typical Pheidole colony structure with distinct major and minor worker castes. Minor workers handle foraging, brood care, and general nest maintenance, while major workers defend the nest and process large food items. Majors have a functional sting and can deliver a mild sting if threatened, though they are not aggressive toward keepers. The species is not known to be invasive or particularly problematic ^[1].
