Nylanderia sharpii

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Native to Hawaii, with populations in China. Found in leaf litter and multiple strata including arboreal, ground, and subterranean levels ^[2][1].
• Colony Type: Colony structure is unconfirmed in available research.
• Size & Growth:
  • Queen: Size data unavailable
  • Worker: Size data unavailable
  • Colony: Up to several hundred workers estimated from related Nylanderia species
  • Growth: Moderate, inferred from genus patterns
  • Development: Estimated 6-8 weeks at optimal temperature, inferred from Formicinae patterns (Development time is inferred as specific data for this species is unavailable)
• Antkeeping:
  • Temperature: Keep warm, roughly 22-26°C, based on tropical distribution, inferred
  • Humidity: Keep substrate consistently moist but not waterlogged, based on leaf litter habitat ^[2]
  • Diapause: Unknown, no specific data available
  • Nesting: Adaptable to test tubes, Y-tong, or plaster nests. Prefer some substrate for burrowing, inferred from habitat ^[2]
• Behavior: Generally calm and non-aggressive. Workers are active foragers. Escape prevention is critical due to small size, inferred from genus patterns.
• Common Issues: escape prevention is critical due to very small size, colonies may be slow to establish, patience needed, wild-caught colonies may carry parasites, overfeeding can lead to mold issues, attraction to lights during nuptial flights

Housing and Nest Setup

Nylanderia sharpii adapts well to various captive setups. Test tubes work excellently for founding colonies, use a standard test tube setup with a water reservoir separated by a cotton plug. For established colonies, Y-tong nests or plaster nests with narrow tunnels work well. These ants will accept both naturalistic setups with soil and more artificial designs. Because they naturally nest in leaf litter and across multiple strata, including some ground contact is beneficial. A small outworld area allows workers to forage. Ensure all connections are sealed with barriers like Fluon due to their small size ^[2].

Feeding and Diet

Like most Formicinae, Nylanderia sharpii is omnivorous. Offer sugar sources such as sugar water or honey as a constant carbohydrate source. For protein, provide small insects like fruit flies or pinhead crickets. Feed protein 2-3 times per week and keep sugar water available. Remove uneaten prey after 24-48 hours to prevent mold ^[1].

Temperature and Seasonal Care

As a species with tropical distribution, keep nest temperatures warm, roughly 22-26°C for optimal growth. A heating cable can create a gradient if room temperature is lower. Diapause is unknown, but based on tropical origin, no true hibernation is likely ^[3].

Colony Founding and Growth

Queens can be caught during nuptial flights on warm, moist evenings, with documented swarms in late August ^[3]. Alates are attracted to lights. Founding behavior is unconfirmed, but after mating, queens may seal themselves in a chamber. The founding phase can take weeks before first workers emerge. Growth is slow initially but accelerates with workers ^[3].

Behavior and Temperament

Workers are active and curious foragers, generally calm and non-aggressive. Their small size means stings are ineffective on humans. Escape prevention is a priority due to their tiny size and exploratory nature ^[2].
