Temnothorax jingzhe

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Yunnan Province, China, found in moss evergreen broadleaf forest at 2450 m elevation in Cangyuan County ^[1]. The high elevation and mossy forest mean they prefer cool, damp, shady conditions.
• Colony Type: Unknown for this species. Based on typical Temnothorax patterns, likely single‑queen colonies, but not confirmed.
• Size & Growth:
  • Queen: Unconfirmed, inferred from genus: probably 4-6 mm
  • Worker: 3.1 mm total length ^[1]
  • Colony: Unknown, estimated up to 100-500 workers based on related species, but not confirmed
  • Growth: Moderate (estimated from genus patterns)
  • Development: Estimated 6-10 weeks based on similar Temnothorax, no direct data (Development time is guessed from related species, actual timing is unknown)
• Antkeeping:
  • Temperature: Keep cool, around 15-20 °C. Their high‑elevation home (2450 m) suggests they prefer lower temperatures than typical room conditions. Avoid heat, not confirmed but inferred from habitat ^[1].
  • Humidity: High humidity, keep nest substrate consistently moist but not waterlogged. Mist occasionally. Habitat is a damp moss forest, so moisture is important.
  • Diapause: Likely required, as a high‑elevation temperate species, a winter rest of 2-3 months at 5-10 °C is probable. Specifics unknown.
  • Nesting: Prefers tight, humid spaces. Test tubes with cotton work for founding. For larger colonies, use Y‑tong (AAC), plaster, or soil nests with small chambers. Keep dark and damp.
• Behavior: Generally peaceful and non‑aggressive. Workers are tiny and move slowly. In the wild they forage in trees, so they climb well, escape prevention is critical because they can slip through standard barriers. They use a smear‑type venom (common to their tribe Crematogastrini) but are not known to sting in a way that hurts humans.
• Common Issues: escape prevention is critical, their tiny 3 mm size lets them get through very small gaps, high elevation origin means they do poorly in warm conditions, keep cool (15-20 °C), humidity must be kept high or colonies will dry out and fail, growth is slow and colony size uncertain, be patient, this is a newly described species with almost no captive care data, all advice is inferred from related ants

Housing and Nest Setup

For a founding colony, a simple test tube setup works. Fill the tube about one‑third with water, plug with cotton, and put the queen in a dark, quiet spot. The queen will seal herself in to raise her first brood, she won't need food until workers appear ^[2]. For established colonies, use Y‑tong (AAC), plaster, or a naturalistic setup with damp soil and moss. Chambers should be narrow because the ants are only 3 mm. Never use acrylic nests, they don't hold humidity well. The outworld (foraging area) can be small, use a plastic container with fluon or a mineral oil barrier on the edges, and fine mesh over ventilation holes. These ants can squeeze through tiny gaps, so double‑check all seals.

Temperature and Heating

Keeping the temperature right is probably the most important factor. Their natural habitat is at 2450 m in a cool, mossy forest, so they prefer temperatures around 15-20 °C ^[1]. Room temperature (20-25 °C) may be too warm, if your home is hot, move the nest to a cooler spot. Avoid direct sunlight and heat sources. In winter, they likely need a hibernation period: gradually lower temperature to 5-10 °C for 2-3 months. This is inferred from their temperate habitat, not confirmed for this specific species.

Feeding and Diet

Temnothorax jingzhe is probably omnivorous, like most Temnothorax. Offer small protein sources such as fruit flies, pinhead crickets, or tiny mealworms, prey items should be no larger than the ants themselves. For carbohydrates, provide a drop of honey water, diluted maple syrup, or sugar water on a piece of foil. Replace sugary foods every few days to avoid mold. Feed small amounts 2-3 times per week. Remove uneaten protein after 24 hours. There are no species‑specific studies, so watch what your colony prefers. ^[2]

Humidity and Water

High humidity is essential, their natural home is a constantly damp moss forest. Keep the nest substrate moist but not waterlogged. In test tube setups, a water reservoir about one‑third of the tube is good, the cotton should feel damp, not dripping. In other nests, check moisture daily and mist when the surface starts to dry. If workers constantly crowd around the water source, humidity is too low. If mold grows quickly, it's too high. Also provide a clean water source in the outworld (e.g., a small tube with cotton). ^[2]

Growth and Development

There is no direct data for this species. Based on related Temnothorax, from egg to first worker (nanitic) takes about 6-10 weeks at 15-20 °C. Growth is moderate, a colony may take 1-2 years to reach around 100 workers. The queen's egg‑laying rate is slow. Colony size is unknown but likely under 500 workers. Overfeeding does not speed growth and can cause mold. ^[2]

Seasonal Care and Hibernation

As a high‑elevation species, Temnothorax jingzhe likely needs a winter diapause. In autumn, when the colony becomes less active, gradually cool them over 1-2 weeks. Keep them at 5-10 °C for 2-3 months (a dedicated refrigerator or cool basement works). Don't let the temperature drop below freezing. Keep the nest slightly moist during hibernation. In spring, warm them slowly back to 15-20 °C. This cycle is inferred from their habitat, not proven. ^[2]
