Temnothorax manni

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Central Mexico (Hidalgo, Morelos, Guerrero) at 2600-2800 m elevation in dry oak-pine woodland ^[1][2].
• Colony Type: Unconfirmed. Based on typical Temnothorax patterns, likely single-queen (monogyne) colonies, but this is inferred and not verified.
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: Unknown
  • Growth: Unknown
  • Development: Unknown (No direct data exists. General Temnothorax species typically take 6-10 weeks for egg-to-worker development at suitable temperatures, but this is an inference.)
• Antkeeping:
  • Temperature: Unknown. Given the high-elevation habitat (2600-2800 m), these ants likely prefer cool conditions (18-22°C). Avoid sustained temperatures above 25°C. Heating is not recommended unless you observe the colony struggling at room temperature.
  • Humidity: Provide a moisture gradient. The natural habitat is dry hillsides, so ants can tolerate quite dry conditions. One end of the nest may be slightly moist (near the water source), while the rest stays dry. Avoid waterlogging.
  • Diapause: Possibly yes, but unconfirmed. High elevation in central Mexico likely brings seasonal temperature drops. If kept in captivity, a mild winter rest of 2-3 months at 10-15°C may be beneficial, but this is speculative. Monitor the colony for signs of reduced activity.
  • Nesting: In the wild, they likely nest in small cavities in rotting wood, under bark, or inside acorns, typical for the genus. In captivity, use test tubes with a water reservoir or small Y-tong (AAC) nests with narrow chambers. Ensure all connections are escape-proof.
• Behavior: Due to lack of documented observations, behavior is inferred from the genus. Temnothorax are generally peaceful and non-aggressive. They have a modified stinger used for smearing venom (subfamily Myrmicinae, tribe Crematogastrini), but they are harmless to humans. Escape prevention is critical because of their small size, they can slip through very narrow gaps.
• Common Issues: care requirements are largely unknown, everything is inferred, so monitor the colony closely and adjust., escape risk is high due to tiny size, use fine mesh, tight cotton plugs, and seal all joints., 25°C) because of their cool natural habitat., colony growth may be slow, but this is speculative., overwatering can be fatal, create a dry zone that reflects their dry hillside habitat.

Housing and Nest Setup

Because detailed nesting biology is unknown, housing is based on general Temnothorax preferences. Use test tubes with a small water reservoir and cotton plug, or a small Y-tong (AAC) nest with narrow chambers. The ants naturally inhabit small cavities (e.g., in rotting wood or under bark) ^[1]. Ensure all connections are escape-proof, these ants are small and can squeeze through tight gaps. A small outworld (10×10 cm) is sufficient for a young colony.

Temperature and Seasonal Care

The only environmental clues come from the collection site: oak-pine woodland at 2600-2800 m elevation, with dry hillsides ^[1]. This suggests a preference for cool conditions. Keep the nest between 18-22°C if possible. Avoid temperatures above 25°C. A winter rest (diapause) is possible but not confirmed, if you live in a region with seasonal temperature changes, you may simulate a mild winter by keeping them at 10-15°C for 2-3 months. Watch the colony for natural signs of reduced activity before inducing diapause.

Feeding and Diet

No dietary data exists for this species. Based on omnivorous habits of most Temnothorax, provide small live prey such as fruit flies (Drosophila) or small pinhead crickets 2-3 times per week. Also offer a constant sugar source (honey, sugar water, or diluted maple syrup). Remove uneaten prey after 24-48 hours. Since workers are small, all food items should be appropriately sized.

Humidity and Water

The natural habitat is described as dry hillsides, so these ants likely tolerate lower humidity than many ant species ^[1]. Provide a moisture gradient: one side of the nest slightly moist (near the water reservoir), the rest dry. Avoid soaking the nest. A test tube setup with a water reservoir gives a natural gradient. Clean water should always be available.

Colony Development

There is no documented colony development for this species. If you manage to start a colony from a wild queen (note: collection may be restricted in Mexico), be patient. General Temnothorax colonies grow slowly, taking weeks to months to produce the first workers. Expect a modest colony size (tens to low hundreds of workers) after several years if conditions are suitable.

Handling and Observation

Ants in this genus are usually non-aggressive. Their defense mechanism is a modified stinger used for smearing venom (smear defense), which is harmless to humans ^[1]. Because of their small size, use good lighting and a dark background for observation. Disturb the nest minimally to avoid stress. Always maintain tight escape prevention.
