Temnothorax lidong

Quick Summary

• Difficulty: Medium
• Origin & Habitat: This species comes from southwestern China, specifically Yunnan and Sichuan provinces at elevations of 1726-1850 meters. They live in monsoon evergreen broadleaf forest and Keteleeria evelyniana forest, foraging on the ground in these cool, humid mountain environments ^[1].
• Colony Type: Unconfirmed. The colony structure of this newly described species has not been studied. Most Temnothorax species are monogyne (single-queen colonies), but without specific data for T. lidong, this cannot be confirmed.
• Size & Growth:
  • Queen: Unconfirmed, no queen measurements published. Based on genus patterns, queens may be around 4-6mm.
  • Worker: 2.3-2.5mm ^[1]
  • Colony: Unconfirmed. Based on typical Temnothorax colonies, small colonies estimated up to 200 workers.
  • Growth: Unknown, no development data. Estimated moderate based on genus patterns.
  • Development: Unconfirmed. Based on similar small Temnothorax species, estimate 6-10 weeks at optimal temperature. (No direct development studies exist for this species. Estimates based on genus-level patterns for small Temnothorax.)
• Antkeeping:
  • Temperature: Likely prefer cool conditions around 18-22°C, based on their natural high-elevation forest habitat (1726-1850 m) ^[1]. Avoid prolonged temperatures above 25°C.
  • Humidity: High humidity preferred. Keep the nest substrate consistently moist but not waterlogged. This species comes from monsoon forest habitat, so aim for a damp microclimate ^[1].
  • Diapause: Likely yes. Based on high-elevation habitat, a winter rest period at 5-10°C for 2-3 months is recommended. Inference from habitat data ^[1].
  • Nesting: Test tubes, Y-tong nests, or plaster nests with small chambers. Provide narrow, cozy spaces that mimic small cavities under stones or rotting wood.
• Behavior: These are tiny, peaceful ants. Workers have a modified stinger used to smear venom onto enemies instead of piercing (smear defense). They forage on the ground and likely form small colonies. Their 2.3mm size means escape prevention is critical, they can squeeze through tiny gaps. They are not aggressive and are best for observation. Like other Temnothorax, they likely use tandem-running to recruit nestmates to food sources.
• Common Issues: escape prevention is critical due to their 2.3mm size, use fine mesh (0.5mm or smaller) and tight-fitting lids., high humidity requirements can lead to mold if ventilation is poor., limited data as a newly described species means some care is based on genus inference rather than species-specific research., slow colony growth can test beginner patience., cool temperature requirements may conflict with room temperature in warm climates.

Housing and Nest Setup

Temnothorax lidong is a tiny ant, so your housing needs to match their small size. Test tubes work well for founding colonies, use a small water reservoir and provide a dark outer covering. For established colonies, Y-tong (AAC) nests with narrow chambers or small plaster nests work better than larger formicariums designed for bigger ants ^[1].

The key is providing appropriately scaled chambers. These ants don't need large spaces, in fact, overly large nests can stress them. A small test tube (15mm diameter or less) works for a founding queen. For a growing colony, use nests with chambers roughly 3-5mm in height and narrow connecting tubes. Avoid the temptation to give them a 'nice big home' right away, they prefer tight, cozy spaces that mimic the small cavities under stones they use in nature.

Keep the nest humid but provide a gradient, some areas slightly damp, others slightly drier so they can choose their preferred microclimate. A layer of substrate at the bottom of the outworld helps maintain humidity.

Temperature and Heating

These are cool-climate ants from high elevation (1726-1850m) in southwestern China. Keep them at 18-22°C, this is cooler than many common ant species and reflects their natural habitat in mountain forests ^[1]. Room temperature is often too warm, especially in summer.

If your room runs warm, you may need to actively cool the nest area rather than heat it. Avoid temperatures above 25°C, prolonged heat stress can kill colonies. In winter, they likely need a cold period (diapause) at 5-10°C for 2-3 months, mimicking the cold winters at their high-elevation habitat.

A simple approach is to keep them in a cool room or basement. If you need to create a temperature gradient, use a very gentle heat source on one side of the nest and monitor with a thermometer. Never place the nest in direct sunlight or near heat sources that could cause temperature spikes.

Feeding and Diet

Like other Temnothorax species, T. lidong is likely omnivorous. They probably eat honeydew from aphids and scale insects, plus small insects and other protein sources. In captivity, offer a mix of sugar sources (honey water, sugar water) and protein (small fruit flies, pinhead crickets, mealworms).

For such tiny ants, the prey needs to be appropriately sized. Fruit flies (Drosophila) are an excellent choice, they're small and easy for workers to tackle. You can also offer tiny pieces of mealworm or other soft-bodied insects. Remove any uneaten prey after 24-48 hours to prevent mold.

Provide a constant sugar source, a small drop of honey water or sugar water refreshed every few days. Because they're so small, even a tiny drop is significant to them. Watch to see what they prefer and adjust accordingly. ^[1]

Humidity and Water

Being from monsoon evergreen broadleaf forest, these ants need higher humidity than many common ant species. Think damp forest floor conditions, the substrate should feel consistently moist but never waterlogged ^[1].

In test tube setups, keep the water reservoir filled but not overflowing. The cotton should be damp but not dripping. For Y-tong or plaster nests, mist the substrate occasionally and monitor for drying. In dry environments, you may need to mist more frequently or use a larger water reservoir.

The key is consistency, avoid cycles of drying out and flooding. These small ants are more sensitive to humidity swings than larger species. A small water dish in the outworld also helps with drinking access.

Colony Growth and Development

As a newly described species (2024), there's no specific development data for T. lidong. Based on typical Temnothorax patterns, expect founding to take several months. The queen will lay eggs, which develop through larval and pupal stages before emerging as nanitic (first) workers ^[1].

First workers will be tiny, even smaller than normal workers. These nanitics help the colony begin foraging and expanding. Growth is typically slow initially, then accelerates once you have 10-20 workers. A mature colony might reach up to 200 workers, though this is an estimate since colony size hasn't been documented.

Be patient, Temnothorax are not fast-growing ants. It can take 6-12 months to get from founding to a stable colony of 20+ workers. Resist the urge to overfeed or disturb the colony frequently. Consistent, appropriate care matters more than intensive attention.

Winter Care and Diapause

Based on their high-elevation habitat in Sichuan and Yunnan provinces, T. lidong likely requires a winter diapause period. These mountains experience cold winters, and the ants would naturally slow down or pause reproduction during this time ^[1].

In captivity, provide a cold period from late autumn through late winter (roughly November through February in the Northern Hemisphere). Reduce temperature to 5-10°C, a refrigerator, unheated garage, or basement can work. Reduce feeding to once or twice monthly during this period.

Do not confuse diapause with simply being cold. True diapause involves physiological changes, but in the hobby, simply providing cold temperatures achieves the same purpose. If your colony is healthy, they'll naturally become less active. Don't be alarmed if they cluster together and move slowly, this is normal winter behavior.

Handling and Behavior

Temnothorax lidong is a peaceful, non-aggressive species. Workers have a modified stinger used to smear venom onto enemies (smear defense) rather than piercing. They're observation ants, fascinating to watch but not interactive in the way some larger species are ^[1].

Their small size means they're excellent escape artists. Even a tiny gap that you'd think nothing could fit through will be exploited. Use fine mesh (0.5mm or smaller) on any ventilation, ensure lid seals are tight, and consider barrier methods like fluon on test tube rims.

In the outworld, they'll forage actively, searching for sugar and prey. They may use tandem-running, one worker leads another to a food source, which is fascinating to observe. Their small size and dark coloration make them somewhat challenging to spot, so watch carefully.
