Pilotrochus besmerus

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Eastern Madagascar, forest habitats at elevations around 1250m. Workers collected from leaf litter samples in humid forest floor environments ^[2][1].
• Colony Type: Unknown, colony structure has never been documented. Only single workers and occasional queens have been collected from litter samples.
• Size & Growth:
  • Queen: Undescribed, queens have been collected but not yet described in scientific literature ^[1].
  • Worker: 2.9mm total length ^[1].
  • Colony: Unknown, no colony has ever been observed or documented.
  • Growth: Unknown
  • Development: Unknown, no development data exists for this species. (All development timelines are estimates based on similar tiny Myrmicinae from Madagascar.)
• Antkeeping:
  • Temperature: Estimated at 24-26°C based on Madagascar forest habitat.
  • Humidity: Keep nest substrate consistently moist but not waterlogged, based on litter-dwelling behavior.
  • Diapause: Unknown, no seasonal data exists. Madagascar has mild seasons, so diapause may not be required.
  • Nesting: Use a test tube setup or small nest with moist soil and leaf litter, inferred from collection data ^[1].
• Behavior: Behavior is unobserved in captivity. Based on related Strumigenys species ^[3], they may be cryptic foragers. Their tiny size means high escape risk, use fine mesh barriers. Aggression level is unknown.
• Common Issues: biology is completely unknown, no one has documented what they eat, how they found colonies, or their basic needs., tiny size makes them extremely difficult to house and feed, standard ant keeping equipment may be too large., no captive breeding success has been documented, wild-caught colonies may not establish., escape risk is extremely high due to their minute size, standard barriers often fail., queens have never been described scientifically, finding a mated queen for sale is essentially impossible.

Why Keep Pilotrochus besmerus?

Pilotrochus besmerus is the only member of its genus ^[1] and a close relative of the trap-jaw ants ^[3]. Keeping this species offers a chance to work with a poorly understood ant, but care is pioneering since no one has kept it before. This is for expert keepers with resources to experiment.

Housing and Setup

Given their tiny size ^[1], standard equipment may be too large. Use a test tube setup with tight cotton barriers or a small nest with moist soil and leaf litter. Keep the nest dark since they are cryptic forest-floor ants.

Feeding and Diet

Diet is unknown ^[1]. Based on related Strumigenys, they may hunt small prey like springtails. Offer live springtails or tiny insect pieces and observe acceptance.

Temperature and Humidity

Based on collection data from eastern Madagascar ^[2], aim for temperatures around 24-26°C with a gentle gradient. Humidity should be high, keep substrate moist but not waterlogged.

Acquiring This Species

This species is rarely collected and queens are undescribed ^[2][1]. It is essentially unavailable to hobbyists, and any listings are likely misidentifications.
