Nylanderia lucayana

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to the Lucayan Archipelago (Bahamas). Collected on North Andros Island under rocks on creek banks at low elevations ^[1][2].
• Colony Type: Not documented in available literature. Based on typical Nylanderia patterns, likely monogyne (single queen), but this is unconfirmed.
• Size & Growth:
  • Queen: Not documented in available literature. Likely around 4–5 mm based on related Nylanderia species, but exact measurements are unknown.
  • Worker: 2.10–2.20 mm ^[1]
  • Colony: Unknown in the wild or captivity. Related Nylanderia species can reach several hundred workers at maturity.
  • Growth: Unknown – expected moderate to fast based on related small Nylanderia species.
  • Development: Estimated 5–8 weeks based on related tropical Nylanderia species at 24–28°C. Specific data for this species has not been published. (This is an estimate from related species. Actual development time may differ.)
• Antkeeping:
  • Temperature: Keep warm at 24–28°C. Because they come from the tropical Bahamas, they need consistent heat. A heating cable on one side of the nest creates a gradient. Room temperature may work if your home stays around 24°C ^[2].
  • Humidity: High – they nest under rocks near creek banks. Keep the nest substrate consistently damp but not waterlogged. Provide a water tube as a permanent moisture source.
  • Diapause: Probably minor or none – from a tropical climate, they don't experience cold winters. A slight cool‑down in winter (down to about 20°C) may be beneficial, but full hibernation is likely unnecessary.
  • Nesting: Enclosed, dark spaces with high humidity. Use a test tube for founding, then move to a small Y‑tong (AAC) or plaster nest. Avoid large ventilation holes – these tiny ants can squeeze through very small gaps. Provide a moist nesting area, like a clump of substrate or a damp sponge.
• Behavior: Fast, erratic foragers – classic 'crazy ant' movement. Not aggressive toward humans. Their small size (2 mm) means escape prevention is critical: use fine mesh on all openings, and seal every connection. They use chemical trails and will follow each other to food. Good climbers.
• Common Issues: tiny size makes escape easy without fine mesh and tight seals., very limited availability – described in 2019,mostly found in the Bahamas., humidity needs are higher than typical room conditions, so you may need to mist the nest regularly., no specific care data exists – many recommendations are inferred from related species., newly mated queens are rarely found, so establishing a colony may depend on rare imports.

Housing and Setup

For founding, use a test tube with water and a cotton plug – the water reservoir keeps humidity high. Once you have workers, transfer to a small Y‑tong (AAC) nest or a plaster nest. Because workers are only 2 mm, all gaps must be sealed. Use fine mesh (0.5 mm or smaller) on ventilation holes. Provide a small outworld for foraging – these ants explore actively. Keep the nest area dark, like their natural spots under rocks. ^[1]

Feeding and Diet

Like other Nylanderia, N. lucayana likely eats a wide range of foods. Offer sugar water or honey constantly as an energy source. For protein, give small insects such as fruit flies, pinhead crickets, or tiny mealworms. Feed protein 2–3 times a week. Remove uneaten prey after 24–48 hours to prevent mold.

Temperature and Seasonal Care

Native to the Bahamas, these ants need warmth. Keep the nest at 24–28°C. A heating cable on one side creates a temperature gradient. They probably don't need full hibernation, but you can lower the temperature slightly in winter (to about 20°C) to mimic natural seasonal changes. Avoid temperatures below 18°C for long periods. High humidity is important – mist the nest if the substrate dries out. ^[2]

Colony Development

Queens likely found colonies without help (claustral founding is common in Nylanderia, but not confirmed here). She will lay eggs and raise the first brood using her stored fat. First workers (nanitics) are smaller than later workers. Expect the first workers in 5–8 weeks at 24–28°C. After that, colony growth should speed up. A mature colony may reach several hundred workers after 1–2 years, but this is estimated.

Behavior and Temperament

Nylanderia lucayana moves fast and erratically like other crazy ants. They are not aggressive toward humans and don't sting effectively. They use chemical trails to recruit nestmates to food. Because they are so small (2 mm), they can escape through tiny gaps – use fine mesh and seal all connections. They are good climbers and will explore vertical surfaces. ^[1]
