Temnothorax zhejiangensis

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Known from Zhejiang, Henan, and Guangxi provinces in China (Oriental Region) ^[2][1]. Specific habitat preferences are unrecorded, likely forested or mountainous areas based on collection localities ^[3].
• Colony Type: Unknown, no colony structure data exists. Based on typical Temnothorax, likely single-queen (monogyne) colonies, but this is unconfirmed ^[3].
• Size & Growth:
  • Queen: Unknown, queen has not been described.
  • Worker: Size data unavailable, only head length measurements exist (0.50-0.58 mm HL), not total body length ^[1].
  • Colony: Unknown, no colony size records.
  • Growth: Unknown, no data.
  • Development: Unknown, no species-specific data. Other Temnothorax species typically take 6-10 weeks at 20-22°C ^[3]. (All development timelines are estimates based on genus patterns. Temperature will significantly affect speed.)
• Antkeeping:
  • Temperature: No species data. For similar Temnothorax species, room temperature (18-24°C) is usually suitable. Avoid extremes ^[3].
  • Humidity: No data. Many small Temnothorax prefer moderate humidity with a dry nest area and slightly moist substrate. Provide a gradient: keep one part of the nest drier and another slightly damp ^[3].
  • Diapause: Likely yes, most Chinese Temnothorax from temperate regions require a winter rest (2-3 months at 5-10°C). However, no specific records exist for this species ^[3].
  • Nesting: Because workers are tiny, use small, tight chambers. Test tubes work for founding, Y‑tong or plaster nests with narrow cavities for larger colonies. Ensure escape‑proof sealing with fine mesh ^[3].
• Behavior: Virtually unknown. Other Temnothorax are generally docile, non‑aggressive, and flee rather than fight. Escape risk is high due to the ant’s tiny size, they can squeeze through very small gaps. Use fine mesh and seal all connections ^[3].
• Common Issues: no species‑specific biology data exists, all care is inferred from genus patterns, very small size means escapes are almost guaranteed without extremely fine barriers (e.g.,0.2 mm mesh), queen unavailable commercially, wild collection may be necessary but biology is unknown, unknown founding behavior, queens may fail if kept dry or cold incorrectly, unknown hibernation needs, wrong temperature or duration could kill the colony

Housing and Nest Setup

Due to the lack of species‑specific data, the following is based on general Temnothorax ant keeping. Because workers are very small, choose housing with tight, narrow spaces. Test tubes are ideal for small colonies, use a small tube with a cotton plug separating the water reservoir from the ants. The confined space mimics natural cavities and helps the queen feel secure ^[3]. For larger colonies, Y‑tong (AAC) or plaster nests with chambers just a few millimetres wide work well. Avoid large, open areas. The nest should have a moisture gradient: one damp area (e.g., moist plaster) and a dry zone. Escape prevention is critical, use very fine mesh (0.2 mm or smaller) on all ventilation holes, apply fluon or petroleum jelly to container rims, and check all seals regularly. A single tiny gap will lead to escapes within hours ^[3].

Feeding and Diet

No diet data exists for this species. In general, Temnothorax accept a standard ant diet: sugar water or diluted honey (1:1) for energy, and small protein sources such as fruit flies, pinhead crickets, or crushed mealworms. Because workers are tiny, pre‑kill or crush larger prey items so the ants can handle them. Feed founding colonies very sparingly, a tiny drop of sugar water every few days and one small insect per week. Overfeeding quickly leads to mould in small nests. Remove uneaten protein within 24 hours ^[3]. As the colony grows, increase portions gradually. Some keepers offer aphids for honeydew, but this is optional ^[3].

Temperature and Seasonal Care

With no documented requirements for Temnothorax zhejiangensis, follow guidelines for related Chinese Temnothorax: maintain room temperature (18-24°C) and avoid sudden fluctuations. Create a small temperature gradient so ants can choose their preferred spot ^[3]. Most temperate Temnothorax need a winter diapause. Plan for 2-3 months at 5-10°C (e.g., in a refrigerator or cool garage). Reduce feeding during this period, and keep the nest slightly damper to prevent desiccation. New colonies in their first year may survive without diapause, but skipping it might affect long‑term health ^[3]. If you are unsure, try a shortened diapause (e.g.,6 weeks) and observe colony response.

Colony Development and Growth

The developmental timeline is unknown. If the queen founds claustrally (a typical Temnothorax pattern), eggs might appear within 2-3 weeks after capture, with first workers emerging around 6-10 weeks later, but this is an estimate ^[3]. Colony growth is likely slow, as in many Temnothorax species. A mature colony may contain from a few dozen to possibly over 100 workers, but no data confirms this. Patience is essential: the first workers (nanitics) are even smaller than normal workers. Disturb the colony as little as possible during founding, bright light and vibrations can stress the queen ^[3].

Behavior and Observation

No behavioral studies exist. By genus patterns, Temnothorax are generally docile, non‑aggressive, and flee from threats. They may use tandem running to recruit nestmates, a primitive form of communication ^[3]. Their tiny size makes detailed observation possible with a magnifying glass. They are active during the day and will show regular activity cycles. Because the species is so poorly known, every colony may behave slightly differently, keep notes to share with the community ^[3].
