Probolomyrmex simplex

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Papua New Guinea, Northern Province near Popondetta ^[1][2].
• Colony Type: Unconfirmed, only workers have been collected, no queens known ^[1].
• Size & Growth:
  • Queen: Unknown, no queens have been collected ^[1].
  • Worker: Size data unavailable, no total length measurements provided ^[1].
  • Colony: Unknown, only five workers are known ^[1].
  • Growth: Unknown ^[1].
  • Development: Unknown, no breeding data exists ^[1]. (No direct data exists.)
• Antkeeping:
  • Temperature: Unknown, no thermal data exists. Based on tropical origin, keep warm, but specifics are unconfirmed ^[2].
  • Humidity: Unknown, no humidity data exists. Based on tropical rainforest habitat, maintain moist conditions ^[2].
  • Diapause: Unknown, tropical species may not require diapause.
  • Nesting: Unknown, no nest data exists. Based on morphology, likely soil or leaf litter nests ^[1].
• Behavior: Unknown, no behavioral observations exist. Based on morphological data, workers are extremely small, so escape risk is high ^[1].
• Common Issues: no established care protocols exist, all advice is speculative ^[1]., tiny size creates severe escape risk requiring excellent barriers ^[1]., extreme rarity makes obtaining founding queens nearly impossible ^[1]., no commercial availability, only wild-caught from PNG would be possible ^[1]., lack of biological data means keepers are pioneering husbandry from scratch ^[1].

Why Probolomyrmex simplex Is an Advanced Keeper's Challenge

This species represents one of the most challenging ants to keep because virtually no biological data exists. Only five workers have ever been collected, all from a single location in Papua New Guinea in 1972 ^[1]. No queens, males, or colony fragments have been documented, meaning keepers must pioneer husbandry from scratch ^[1]. This makes P. simplex a species for expert keepers only, ideally those with experience establishing new species from limited data ^[1].

Housing and Nest Setup

No specific housing data exists for Probolomyrmex simplex. Based on their tiny size and eyeless morphology, they may require dark, humid nests with small chambers ^[1]. Use Y-tong or plaster nests with moisture control, and provide a deep outworld with moist soil for foraging. Escape prevention is critical due to their minute size ^[1].

Feeding and Nutrition

No feeding data exists for this species. Based on Proceratiinae biology, they are likely predatory on small soil invertebrates ^[2]. Offer live springtails or grain mites, and avoid larger prey due to their size. Sugar sources may be accepted occasionally, but protein should form the primary diet.

Temperature and Seasonal Care

No thermal data exists for this species. As a tropical species from Papua New Guinea, keep temperatures warm and stable, roughly 24-28°C, but specifics are unconfirmed ^[2]. Humidity should be maintained based on habitat, but no exact data exists ^[2]. Diapause is unknown, but tropical species may not require it.
