Nylanderia scintilla

Quick Summary

• Difficulty: Unknown, Insufficient Data
• Origin & Habitat: West Africa (Ivory Coast, Nigeria), found in urban green spaces in the Abidjan district ^[2][1]
• Colony Type: Unknown, queen caste has never been documented ^[1]
• Size & Growth:
  • Queen: Unknown, queen caste currently unknown ^[1]
  • Worker: 1.8-2.0 mm total length ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown, no development data available
  • Development: Unknown, no direct measurements available (No development timeline data exists. Related Nylanderia species in the tropics typically take 4-8 weeks from egg to worker, but this is a rough estimate.)
• Antkeeping:
  • Temperature: Likely 24-28°C based on West African origin, no direct data available
  • Humidity: Keep the nest substrate consistently moist but not waterlogged, typical of tropical ground-nesting ants, no direct data available
  • Diapause: Unknown, West African ants usually do not enter true diapause, but may slow down during cooler or drier periods
  • Nesting: Likely nests in soil or rotting wood cavities, based on genus patterns, no direct observations available ^[1]
• Behavior: Behavior is unstudied. Based on genus patterns, Nylanderia species are small, active foragers that collect honeydew and hunt small prey. Their tiny size (under 2 mm) makes them excellent escape artists, fine mesh barriers are essential. They are unlikely to be aggressive and probably nest in soil or under stones. Any sting would be negligible to humans due to their size.
• Common Issues: no documented colony founding behavior, unknown if claustral or semi-claustral, queen caste unknown, cannot determine colony structure (single-queen vs. multiple-queen), no development timeline data makes timing predictions impossible, escape prevention is critical due to tiny 2 mm worker size, no information on temperature or humidity preferences, keepers must experiment carefully

Appearance and Identification

Nylanderia scintilla workers are among the smallest ants you'll keep, measuring just 1.8-2.0 mm in total length ^[1]. They are brownish-yellow with distinctly lighter antennae and legs, this contrast is helpful for identification ^[1]. The cuticle is smooth and shining, and the gaster has a dense layer of short hairs that gives it a silky look ^[1]. The head is roughly square with angular corners, and the antenna scapes extend past the back of the head by about the length of the first 2-3 funicular segments ^[1]. The key feature that separates this species from similar Nylanderia is that all leg bases (coxae) are the same color, in the close relative N. boltoni, the middle and hind coxae are lighter ^[1].

Distribution and Habitat

This species is currently known only from West Africa: Ivory Coast (collected at Palmeraie Lame) and Nigeria (Gambari) ^[1]. Surveys in the Abidjan district of Ivory Coast found them in urban green spaces, suggesting they can handle human-modified environments ^[2]. They were most common in certain park areas, with 12-14 occurrences at two sites ^[2]. Their natural nesting habitat, whether forest floor, savanna, or something else, is unknown.

What We Don't Know

There is very little known about this species. The queen caste has never been described, we have no information on queen size, color, or body shape ^[1]. The male caste is also unknown. As a result, we cannot tell whether colonies are single-queen (monogyne) or multiple-queen (polygyne), nor if they have ergatoid replacement queens. Colony founding behavior is a mystery: no one has observed whether queens found claustrally or semi-claustrally. There is no data on development times, temperature or humidity preferences, or diet. Keepers will need to document their own observations to fill these gaps.

Care Recommendations

No direct care data exists for this species, so recommendations are based on related Nylanderia and general principles for tiny tropical ants. Aim for a nest temperature of 24-28°C, matching their West African origin. Keep the nest substrate consistently moist but not waterlogged, think damp soil, not puddles. Use a test tube setup or a small nest with chambers sized for 2 mm ants. Because of their tiny size, escape-proofing must be excellent: standard test tube cotton may be too loose, consider fine mesh barriers. Feed sugar water or honey as a constant energy source, and offer very small protein sources like fruit flies or pieces of mealworm. Start with tiny prey and watch to see if they accept it.

Related Species Context

Nylanderia scintilla is closely related to Nylanderia boltoni and Nylanderia umbella, based on worker morphology ^[1]. The genus Nylanderia includes many small, ground-nesting species found in warm climates worldwide. Some Nylanderia have become invasive in places far from their native range, but N. scintilla's known distribution is limited to West Africa. Many Nylanderia are polygynous, but we cannot assume this for N. scintilla without direct observation. The genus belongs to the subfamily Formicinae, which also includes Camponotus and Lasius. Most Formicinae are non-aggressive and do not sting.
