Nylanderia ambulator

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Central America (Honduras to Costa Rica) in low-to-moderate elevation (30-750 m) primary/secondary rainforest and cloud forest, living in leaf litter ^[1][2].
• Colony Type: Unconfirmed, based on Nylanderia genus patterns, likely monogyne (single queen), but colony structure has not been specifically documented for this species.
• Size & Growth:
  • Queen: ~3.4-3.7 mm ^[1]
  • Worker: ~1.7-2.1 mm ^[1]
  • Colony: Size data unavailable for maximum colony size.
  • Growth: Moderate, estimated based on similar tropical Nylanderia species
  • Development: Estimated 6-8 weeks at tropical temperatures, based on genus-level patterns (Direct development data unavailable, expect relatively fast development given tropical origin.)
• Antkeeping:
  • Temperature: Keep at warm temperatures, roughly 22-26°C, based on tropical habitat ^[2].
  • Humidity: Keep nest substrate consistently moist but not waterlogged, mimicking leaf litter habitat ^[2].
  • Diapause: No, being a tropical species, they do not require hibernation.
  • Nesting: Prefer humid setups with fine substrate like soil or peat, or test tubes for founding colonies. Use Y-tong, plaster, or 3D-printed nests, not acrylic.
• Behavior: Active foragers, not aggressive, but escape risk due to tiny size (around 2 mm). Workers move quickly and may scatter when disturbed.
• Common Issues: escape prevention is critical due to tiny worker size, they can squeeze through standard barriers, high humidity requirements can lead to mold if ventilation is poor, tropical species may struggle in air-conditioned rooms or drafty environments

Housing and Setup

For a newly founded colony, a standard test tube setup works well. Use a small test tube with a water reservoir separated by a cotton plug. Keep the tube horizontal with the cotton end slightly elevated. Cover the tube with a dark cloth during founding ^[2]. Once the colony reaches 20-30 workers, move to a formicarium with small chambers. Use Y-tong, plaster, or 3D-printed nests to maintain humidity. Add an outworld with fine mesh barriers and fluon on rims to prevent escapes ^[2].

Feeding and Diet

Nylanderia ambulator is a generalist feeder. Offer sugar water (honey or sugar solution) constantly, and protein sources like fruit flies or small insects 2-3 times weekly. Remove uneaten food to prevent mold ^[2].

Temperature and Humidity

Keep nest area at warm temperatures, roughly 22-26°C, using a heating cable on one side for a gradient. Humidity is critical, keep substrate moist but not waterlogged, mimicking leaf litter habitat ^[2].

Colony Development

As a newly described species, specific development data is unavailable. Based on genus patterns, expect first workers 6-8 weeks after founding at warm temperatures. Colony growth is moderate, with size data unavailable ^[2].

Behavior and Handling

Workers are active and quick-moving, typical of Nylanderia. They are not aggressive but may scatter when disturbed. Escape prevention is critical due to tiny size ^[1].

Seasonal Care

No diapause is needed as a tropical species. Maintain consistent warmth and humidity year-round ^[2].
