Nesomyrmex sellaris

Quick Summary

• Difficulty: Unknown
• Origin & Habitat: Eastern Madagascar, from tropical dry forests to rainforests at elevations of 20-1130 meters ^[1]
• Colony Type: Unconfirmed, no data on queen number or colony structure
• Size & Growth:
  • Queen: Size data unavailable
  • Worker: Size data unavailable
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown, no direct measurements. Based on typical Nesomyrmex patterns, estimate 6-10 weeks at tropical temperatures, but this is inferred. (No specific development data exists for this species.)
• Antkeeping:
  • Temperature: Start around 22-26°C and observe colony behavior. As a Madagascar lowland species, they likely prefer warm conditions. Provide a gentle temperature gradient if possible ^[2].
  • Humidity: Keep nest substrate consistently moist but not waterlogged. Their wild habitat spans dry to wet forests, so they tolerate a range ^[2].
  • Diapause: Unknown, Madagascar species may not require strong diapause, but activity may slow during cooler periods.
  • Nesting: Use test tube setups or small nests with moist substrate. Provide minimal disturbance during founding ^[2].
• Behavior: Behavior is unstudied, but as a tiny Myrmicinae, they are likely docile. Their primary defense is a smear mechanism using a modified stinger, typical of their subfamily. Escape risk is high due to small size, use fine mesh barriers.
• Common Issues: limited biological data makes care experimental, monitor closely for stress, small size increases escape risk, use fine mesh and secure barriers, unknown founding behavior may challenge colony establishment, diet acceptance is unstudied, start with standard ant foods and observe

Appearance and Identification

Nesomyrmex sellaris workers are small ants with a uniform yellow body color. The most distinctive feature is the deep mesopropodeal depression, a saddle-like groove between the mesonotum and propodeum, reflected in their name 'sellaris' ^[1]. They have fine foveae on the head and shiny, imbricate sculpture. Exact body size is not documented in available research.

Natural Distribution and Habitat

This species is endemic to eastern Madagascar, found in diverse habitats from tropical dry forests to rainforests at elevations of 20-1130 meters ^[1]. This broad range indicates adaptability to varying humidity and temperature conditions, useful for captive care.

Housing and Nesting

No specific natural nesting data exists, but as small Myrmicinae, they do well in test tube setups or small nests with moist substrate. Provide minimal disturbance during founding. Escape prevention is critical due to their tiny size, use fine mesh barriers ^[2].

Feeding and Diet

No species-specific dietary studies exist. As small ants, they likely accept sugar sources like honey water and small protein prey such as fruit flies or springtails. Offer small amounts every few days and remove uneaten food ^[2].

Temperature and Seasonal Care

As a Madagascar lowland species, they prefer warm conditions around 22-26°C. Provide a temperature gradient for self-regulation. Diapause requirements are unknown, but activity may slow in cooler months ^[2].
