Temnothorax hispaniolae

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to the Dominican Republic (Hispaniola), found at elevations between 610-2,000 m in La Vega Province ^[2][3]. They opportunistically nest in small hollow cavities including dead twigs, sticks on the ground, and rot holes in trees ^[2]. This is an arboreal lineage within the sallei group ^[4].
• Colony Type: Likely single-queen colonies (monogyne), which is typical for most Temnothorax species. No specific data on multi-queen colonies exists for this species.
• Size & Growth:
  • Queen: 6.1 mm ^[1]
  • Worker: 3.1-4.2 mm ^[1]
  • Colony: Likely small colonies of several dozen to a few hundred workers, typical of the genus
  • Growth: Moderate
  • Development: Estimated 6-10 weeks based on typical Temnothorax development patterns (Development time inferred from genus-level data, specific timing for this species has not been documented)
• Antkeeping:
  • Temperature: Based on elevation range (610-2,000 m), maintain temperatures around 20-24 °C. Avoid extremes above 28 °C or below 15 °C. Provide a temperature gradient within the setup ^[2][3].
  • Humidity: Keep the nest substrate moderately moist, not waterlogged. Provide a humidity gradient with one damp area and one drier area so the ants can choose their preferred zone. These cavity nesters do well with some damp substrate.
  • Diapause: Specific diapause requirements are unknown. As a species from moderate elevations in the Dominican Republic, there may be a period of reduced activity during cooler months. If the colony slows down, consider a cooler period (15-18 °C) for 2-3 months, but this is not confirmed.
  • Nesting: Provide small cavities, test tubes work well for founding colonies. As they naturally nest in hollow twigs and small cavities, they prefer tight-fitting chambers rather than large open spaces. For established colonies, use Y-tong (AAC) nests, plaster nests, or 3D-printed nests with narrow chambers.
• Behavior: These ants are aggressive and pugnacious, Bill Brown reportedly described their stings as intense despite their small size ^[2]. They are active foragers and will defend their nest vigorously. Workers are small (3-4 mm) so escape prevention is important, use fine mesh and tight-fitting barriers. They are arboreal cavity nesters by nature and will readily colonize small artificial nests.
• Common Issues: small size means escapes are likely without fine mesh barriers, aggressive defense requires careful handling, they will sting, colonies stay small, don't expect large worker counts, test tube water reservoir must be properly sealed with cotton to prevent flooding, wild-caught queens may carry parasites, check for health before introducing

Housing and Nest Setup

Temnothorax hispaniolae does well in small, cavity-based nests that mimic their natural hollow twig nesting preferences. For founding colonies, a standard test tube setup works excellently, fill one-third with water, plug with cotton, then connect to an outworld. The tube should be dark to simulate the interior of a hollow twig or branch. For established colonies, Y-tong (AAC) nests, plaster nests, or 3D-printed nests with narrow chambers work well. Avoid large, open spaces, these ants feel safest in tight chambers scaled to their tiny size. Provide a humidity gradient by placing part of the nest on moist plaster or soil while keeping another section drier ^[2][3].

Feeding and Diet

Like most Temnothorax species, Temnothorax hispaniolae is omnivorous. Offer protein sources such as small insects (fruit flies, small mealworms, pinhead crickets) and sugar sources (honey water, sugar water). Feed small prey items that match the worker size, these are tiny ants, so appropriately sized food is important. Provide protein 2-3 times per week and keep a constant sugar source available. Remove uneaten prey after 24-48 hours to prevent mold. In the wild, they likely forage for small arthropods and tend aphids for honeydew.

Temperature and Seasonal Care

Based on their elevation range (610-2,000 m), maintain temperatures around 20-24 °C for optimal colony development. Avoid extreme heat above 28 °C or cold below 15 °C. Provide a temperature gradient so workers can self-regulate by moving between warmer and cooler areas. During winter, you can reduce temperatures to 15-18 °C if the colony shows reduced activity, this may simulate their natural seasonal cycle, though specific hibernation requirements are not confirmed ^[2][3].

Behavior and Defense

Temnothorax hispaniolae is notably aggressive and pugnacious for such a small ant. Workers will readily defend the nest and are capable of delivering a surprisingly painful sting for their size ^[2]. When working with this species, use caution, they are quick to respond to perceived threats. They are active foragers and will send workers out to collect food. Their small size (3-4 mm workers) means they can escape through tiny gaps, so excellent escape prevention with fine mesh is essential. Despite their small size, do not underestimate their defensive capabilities.

Colony Development

Colonies remain relatively small throughout their lifecycle, typical of the genus Temnothorax. Expect colonies to grow slowly but steadily over the first year. A mature colony likely contains only several dozen to a few hundred workers. Founding behavior is unconfirmed, no specific data exists on whether queens are claustral or semi-claustral. The first workers (nanitics) are typically smaller than mature workers. Patience is key with this species, as growth is gradual compared to faster-growing genera like Camponotus or Lasius.
