Temnothorax salvini

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to Central America (Costa Rica, Guatemala, Honduras, Mexico, Panama). Inhabits mid-to-high elevation cloud forests, typically above 1,500 m. Believed to be an arboreal nester, nesting in dead twigs, hollow vines, or under epiphyte roots ^[1][2].
• Colony Type: Strictly monogyne, each colony has a single queen, as confirmed by all nest collections ^[2].
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: unknown, not documented in research
  • Growth: moderate, inferred from related Temnothorax species
  • Development: estimated 6-8 weeks based on typical Temnothorax development (No specific data for T. salvini, timeline inferred from genus.)
• Antkeeping:
  • Temperature: Maintain warm, stable temperatures reflecting cloud forest habitat. Probably around 22-26°C, but no exact data. Avoid prolonged temperatures below 20°C or above 30°C.
  • Humidity: High humidity required, aim for moist substrate and good ventilation. Cloud forests are perpetually damp. Keep nest substrate consistently moist but not waterlogged.
  • Diapause: No, tropical species, no evidence of diapause. Keep warm year-round.
  • Nesting: Arboreal nester ^[1]. Provide small cavities: dead twigs, hollow vines, or Y-tong/formicarium with narrow chambers scaled to their tiny size. Avoid large open spaces.
• Behavior: Peaceful and non‑aggressive. Forages actively in vegetation. Their small size makes escape prevention critical, use fine mesh (
• Common Issues: escape prevention is critical due to very small size, they can squeeze through tiny gaps., high humidity needs can lead to mold if ventilation is poor, balance moisture and airflow., wild‑caught colonies may harbor parasites., temperatures below 20°C may cause decline, keep warm and stable.

Housing and Nest Setup

Temnothorax salvini is an arboreal nesting species, so your setup should reflect their natural preference for small cavities. In the wild, they nest in dead twigs, hollow vines, and under the roots of epiphytes in cloud forests ^[1][2]. For captivity, a Y-tong (AAC) nest or plaster formicarium with narrow chambers works best. The chambers should be scaled to their tiny worker size, tight spaces help them feel secure. A test tube setup can work for founding colonies, but monitor humidity carefully as test tubes can flood or dry out. If using a naturalistic setup, provide small dead twigs or cork bark pieces as nesting material. Always use excellent escape prevention, these tiny ants can slip through gaps that larger species cannot. Apply fluon to any edges or use fine mesh (at least 0.5mm) on any ventilation holes.

Temperature and Humidity

Being from Central American cloud forests, T. salvini needs warm and humid conditions. Keep temperatures in the range of 22-26°C, this mimics the stable, warm climate of their natural habitat at higher elevations. Avoid temperatures below 20°C, as prolonged cold can weaken or kill colonies. For humidity, aim for moist conditions: cloud forests are perpetually damp, so these ants have not adapted to dry conditions. Keep the nest substrate consistently moist but not waterlogged. You can achieve this by using a water reservoir connected to the nest or by misting regularly and monitoring with a hygrometer. Good ventilation is still necessary to prevent mold, but avoid excessive airflow that dries the nest out. ^[2]

Feeding and Diet

Like other Temnothorax species, T. salvini is likely omnivorous with a preference for protein. Offer small protein sources such as fruit flies, small crickets, mealworms, or other appropriately-sized insects. They will also accept sugar sources like honey water or sugar water, especially when the colony grows larger. In their natural cloud forest habitat, they likely forage for honeydew from aphids and scale insects, so sugar sources are important for energy. Feed small amounts every 2-3 days and remove any uneaten food to prevent mold. A constant supply of sugar water is recommended for established colonies.

Colony Development

Temnothorax salvini colonies are strictly monogyne, meaning each colony has a single queen ^[2]. This was confirmed in all documented nest collections from the wild. The founding behavior (e.g., claustral or semi‑claustral) is unconfirmed because no direct observations have been published. First workers (nanitics) will be smaller than mature workers. Based on typical Temnothorax development, expect the first workers to emerge 6-8 weeks after the queen lays eggs, assuming optimal temperatures around 26°C. Colony growth is moderate, these ants do not produce massive colonies like some Myrmicinae, and maximum size is unknown. Be patient during the founding phase as the colony is most vulnerable at this stage.

Seasonal Care

As a tropical species from Central American cloud forests, T. salvini does not require diapause or winter hibernation. Maintain consistent temperatures year-round without seasonal drops. The cloud forest environment they come from is relatively stable climatically, so they have not evolved adaptations for cold periods. Do not attempt to cool the colony for winter, this can be fatal. Simply maintain the same care routine throughout the year. If your room temperature naturally fluctuates with seasons, use a heating mat or thermostat to keep conditions stable.
