Temnothorax tyndalei

Temnothorax tyndalei

Temnothorax tyndalei is a tiny, reddish-brown ant measuring just 3-4mm in worker size ^[1]. This species belongs to the Myrmicinae subfamily and is found across the Ibero-Maghreb region, specifically Algeria and Morocco in North Africa, with scattered populations across the Iberian Peninsula in Spain and Portugal ^[2][3]. The species was originally described as a subspecies of Temnothorax tuberum in 1909 and was raised to full species status in 1966 ^[1]. These ants are part of the 'cryptic species' functional group, meaning they prefer to hide in small, concealed spaces rather than building obvious nests ^[4]. They are associated with relatively humid, shaded forest habitats and are typically found in mountainous areas or woodland environments ^[4].

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to the Ibero-Maghreb region, Algeria, Morocco, Spain, and Portugal. Found in humid, shaded forest habitats including olive groves, mountain forests, and riparian woodlands at elevations up to 1289m ^[3][2].
• Colony Type: Single-queen colonies (monogyne), typical for the genus. Colony size is unknown but likely small, typical of Temnothorax species.
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 5-6mm based on genus typical size
  • Worker: 3-4mm ^[1]
  • Colony: Likely under 500 workers based on genus patterns
  • Growth: Moderate
  • Development: Estimated 6-10 weeks at optimal temperature based on related Temnothorax species (Development time is unconfirmed for this specific species, estimates based on typical genus behavior)
• Antkeeping:
  • Temperature: Keep at 18-24°C. This species comes from temperate regions with moderate temperatures, so avoid extreme heat. A room-temperature setup around 20-22°C works well.
  • Humidity: Moderate to high, they prefer humid forest floor conditions. Keep the nest substrate slightly moist but not waterlogged, with some drier areas for the ants to choose ^[4].
  • Diapause: Yes, as a temperate species from the Mediterranean region, they likely require a winter rest period of 8-12 weeks at 10-15°C.
  • Nesting: Soil-nesting species. In captivity, they do well in test tubes, Y-tong nests, or plaster nests with small chambers. Provide tight, snug chambers since they are a cryptic species that prefers confined spaces ^[4].
• Behavior: These ants are shy and non-aggressive. Workers are small and slow-moving, foraging individually or in small groups. They are not known to sting and pose no danger to keepers. Escape prevention is critical due to their tiny size, they can squeeze through standard test tube barriers. They prefer to stay hidden in small crevices and chambers ^[4].
• Common Issues: escape prevention is critical, their tiny size means they can slip through standard barriers easily, limited biological data means care is based on genus defaults rather than species-specific research, sensitive to drying out, keep nest substrate consistently moist, slow colony growth can frustrate beginners who expect rapid development, wild-caught colonies may be difficult to establish due to unknown founding requirements

Housing and Nest Setup

Temnothorax tyndalei is a soil-nesting species that prefers tight, enclosed spaces. In captivity, they do well in standard test tubes with a water reservoir, Y-tong (AAC) nests with small chambers, or plaster nests designed for small Myrmicinae ^[4]. Since they are a cryptic species, provide chambers that are snug rather than spacious, these ants feel most secure in tight spaces. A naturalistic setup with a thin soil layer and flat stones on top also works well, mimicking their natural forest floor habitat. Ensure the nest has good humidity retention while allowing some ventilation to prevent mold. Because of their tiny size, use fine mesh on any openings and consider double-barrier systems for escape prevention ^[2].

Feeding and Diet

Like most Temnothorax species, these ants are omnivorous with a preference for small protein sources and sugar. Offer small insects like fruit flies, pinhead crickets, or tiny mealworms as protein. They will also accept sugar water, honey, or diluted honey water placed on a small piece of cotton or sponge. Feed small amounts 2-3 times per week, removing any uneaten prey after 24 hours. Since workers are tiny, prey items should be appropriately sized, no larger than the ant's head. Sugar should be available constantly, either as a soaked cotton ball or commercial ant sugar water. Fresh water should always be accessible.

Temperature and Seasonal Care

Keep the nest area at 18-24°C, with room temperature around 20°C being ideal. This species comes from temperate Mediterranean regions with moderate climates, so avoid temperatures above 28°C or below 15°C. During winter (roughly November through February in the Northern Hemisphere), reduce temperatures to 10-15°C to provide a diapause period. This winter rest is important for colony health and may trigger spring reproduction. Do not cool them suddenly, reduce temperatures gradually over 2-3 weeks. Keep the colony in a location away from direct sunlight and heating vents that could cause temperature fluctuations ^[4][3].

Humidity Requirements

Temnothorax tyndalei prefers moderate to high humidity, reflecting their association with humid forest habitats in the wild ^[4]. Keep the nest substrate consistently moist but never waterlogged. The substrate should feel damp to the touch but not have standing water. You can achieve this with a properly sized water reservoir in a test tube setup, or by lightly misting the nest area and allowing it to dry naturally before rehydrating. Watch for condensation on test tube walls, a small amount is normal and indicates good humidity, but excessive condensation can drown small colonies. Provide a gradient by having one area slightly drier so ants can self-regulate.

Colony Establishment

If you acquire a founding queen (claustral), she will seal herself into a small chamber and raise the first brood alone without foraging. Provide a small test tube setup with a water reservoir and keep it undisturbed in a dark place at around 20°C. The queen will lay eggs and, after 2-4 weeks, you should see larvae. First workers (nanitics) typically emerge 6-10 weeks after founding, though this is estimated based on typical genus behavior since specific data for T. tyndalei is unavailable. Once workers emerge, you can begin offering tiny food items. Do not disturb the founding chamber unnecessarily, stress can cause queens to abandon or eat their brood. If acquiring an established colony, transfer it gently to an appropriate nest setup with similar humidity conditions.

Behavior and Observation

This species is calm and non-aggressive, making them interesting to observe but not exciting for those wanting dramatic ant behavior. Workers forage individually or in small groups, exploring their environment slowly. They are not known to sting and will only bite if severely threatened, with minimal effect. The most notable behavior is their preference for hidden, cryptic nesting, you may rarely see workers out in the open unless foraging. They are most active during evening and night hours. Because they are small and fast-moving, observation is best done with a magnifying glass or under good lighting. Their small colony size means you can observe the entire colony structure easily, including the queen if she ventures out. ^[4]
