Temnothorax dahan

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to Yunnan Province, China (Wenshan City area). Found in subalpine moist evergreen broadleaf forest and Pinus yunnanensis forest at 2027-2530 m elevation ^[1]. This high-elevation habitat suggests they prefer cool, humid conditions.
• Colony Type: Likely single-queen colonies based on typical Temnothorax patterns. Colony founding behavior is unconfirmed ^[2].
• Size & Growth:
  • Queen: Undocumented. Queen specimens were not collected during the type description. Based on typical Temnothorax queen sizes, they are estimated at around 4-5 mm ^[2].
  • Worker: 2.5-2.8 mm ^[1]
  • Colony: Estimated up to several hundred workers based on related species ^[2].
  • Growth: Moderate
  • Development: Estimated 6-10 weeks based on related Temnothorax species ^[2]. (Development time is inferred from genus-level data. Temperature will affect this timeline.)
• Antkeeping:
  • Temperature: Based on their high-elevation habitat, they likely prefer cool temperatures around 18-22°C. Avoid temperatures above 25°C. A gentle temperature gradient allows them to regulate ^[1].
  • Humidity: Moderate to high humidity. Keep the nest substrate moist but not waterlogged. Their natural habitat in moist forests suggests they need consistent dampness ^[1].
  • Diapause: Likely yes. Yunnan winters are cold, so expect a 2-3 month rest period during winter. Reduce feeding and keep them around 10-15°C during this time ^[2].
  • Nesting: Soil-nesting species confirmed by research ^[1]. In captivity, use a setup with moist soil or a plaster nest with soil chambers. They prefer tight, enclosed spaces, avoid tall, open areas.
• Behavior: Generally peaceful and non-aggressive. Like most Temnothorax, they flee rather than fight. They have a modified stinger used to smear venom onto threats rather than pierce (typical of Crematogastrini), but they are harmless to humans. Their tiny size makes escape prevention critical, they can fit through gaps under 0.5 mm ^[2].
• Common Issues: tiny size makes escape prevention critical, use fine mesh and tight lids., limited data as a newly described species, care relies on genus patterns., high-elevation origin means they may struggle in warm rooms, monitor temperature., soil nesting requires careful humidity to prevent mold and drowning., wild-caught colonies may harbor parasites that can devastate a colony.

Housing and Nest Setup

Temnothorax dahan nests in soil ^[1]. A naturalistic setup with moist soil in a shallow container works well, or you can use a plaster or acrylic nest with soil-filled chambers. The key is to provide tight, enclosed spaces scaled to their tiny size, large chambers cause stress. Connect a small outworld for foraging. Seal all gaps with cotton or fine mesh, because these 2.5 mm ants can slip through openings larger than 0.5 mm ^[2].

Feeding and Diet

Like other Temnothorax, these ants are omnivorous with a preference for protein. Offer small live prey such as fruit flies, pinhead crickets, or tiny insects. They also accept sugar sources like honey water or sugar water. Feed protein 2-3 times per week and provide a constant sugar source (e.g., a cotton ball soaked in honey water). Remove uneaten prey after 24 hours to prevent mold. Their small size means prey items must be appropriately sized, anything larger than themselves may be ignored ^[2].

Temperature and Seasonal Care

This species comes from high-elevation Yunnan forests where temperatures stay cool year-round ^[1]. Keep the nest area at 18-22°C, avoid exceeding 25°C. A heating cable on one side creates a gradient. During winter (roughly November through February), expect a natural slowdown. This is their diapause period, reduce feeding and keep them at 10-15°C. Do not skip hibernation entirely as it is important for colony health ^[2].

Behavior and Colony Dynamics

Temnothorax dahan displays the calm, non-aggressive temperament typical of the genus. Workers are shy and flee when threatened. They have a modified stinger used to smear venom (not pierce), but they pose no danger to keepers. Colonies grow gradually, the first workers (nanitics) will be smaller than mature workers. Queens remain hidden in the nest, tended by workers ^[2].

Handling and Observation

These ants are best observed, not handled. Their small size and speed make them delicate. Watch through the nest walls or in the outworld during feeding. You may notice tandem running (one worker leading another to food). Minimize disturbance during the founding stage to avoid stress. Once the colony is established, occasional feeding and nest maintenance are enough ^[2].
