Nylanderia wardi

Quick Summary

• Difficulty: Medium, based on genus patterns, but species-specific data is lacking
• Origin & Habitat: Cuba, Holguin province, found at 25m elevation in forest edge areas ^[1].
• Colony Type: Unconfirmed, colony structure has not been documented in scientific literature
• Size & Growth:
  • Queen: Not described, no queen measurements exist ^[1]
  • Worker: 2.20-2.84 mm total length ^[1]
  • Colony: Unknown, no colony size data exists
  • Growth: Unknown, no development data exists
  • Development: Unknown, but estimated 4-8 weeks based on typical Nylanderia genus patterns (Development likely depends on temperature, no species-specific data exists)
• Antkeeping:
  • Temperature: Estimated 24-26°C based on Cuban tropical habitat, provide a gradient
  • Humidity: Keep substrate consistently moist but not waterlogged, based on tropical climate
  • Diapause: Unknown, likely minimal given tropical distribution
  • Nesting: Use test tube setup for founding, once established, small formicarium with moist substrate
• Behavior: Based on Nylanderia genus patterns, they are fast-moving, active foragers with erratic movement. They are likely generalist feeders. Their small size means escape prevention is critical.
• Common Issues: tiny size makes escape prevention essential, they can squeeze through small gaps, no species-specific care data exists, start with general Nylanderia parameters and adjust, founding behavior unconfirmed, assume caution when introducing queens, colony size unknown, monitor growth and adjust resources as needed

Discovery and Naming

Nylanderia wardi was formally described in 2019 by LaPolla and Kallal as part of a review of Nylanderia species in the West Indies ^[1]. The species is named after Philip S. Ward, who collected the type specimens ^[1]. The type locality is in Holguin province, Cuba, approximately 6 kilometers south of Yamanigüey, at 25 meters elevation ^[1].

Identification and Appearance

Workers of Nylanderia wardi are small ants measuring 2.20-2.84 mm in total length ^[1]. They are light brown to brownish-yellow, with slightly darker dorsal surfaces ^[1]. The head is ovate when viewed from the front, with rounded corners ^[1]. They have well-developed eyes and a median ocellus ^[1]. This species is larger than the similar N. sierra and has a longer slope between the mesonotum and metanotal area ^[1].

Known Range and Habitat

Nylanderia wardi is currently known only from Cuba, specifically Holguin province in the eastern part of the island ^[1]. The type specimens were collected at 25 meters elevation in what appears to be a tropical forest edge area ^[1]. Cuba has a tropical climate with warm temperatures and moderate humidity ^[1].

Care Recommendations

Since no biological data exists specifically for N. wardi, care recommendations are based on typical Nylanderia genus behavior. Provide a temperature around 24-26°C and keep substrate moist but not waterlogged ^[2]. They likely accept sugar sources like honey water and small protein like fruit flies ^[2]. For founding, use a test tube setup, once established, a small formicarium with moist substrate works well. Given their tiny size, ensure excellent escape prevention with fine mesh ^[2].

Comparison with Similar Species

Nylanderia wardi is very similar to N. sierra, but N. wardi is larger and has a longer slope between the mesonotum and metanotal area ^[1]. N. wardi also has more large bristles on the antennae ^[1]. Despite overlapping ranges, the two species maintain distinct differences ^[1].
