Temnothorax tesquorum

Quick Summary

• Difficulty: Easy
• Origin & Habitat: North Caucasus region (between the Black Sea and Caspian Sea), likely found in mountainous rocky areas ^[1][2]
• Colony Type: Unknown. Based on typical Temnothorax patterns, likely single-queen (monogyne), but no data has been recorded.
• Size & Growth:
  • Queen: Size data unavailable, typical Temnothorax queens are around 5-6mm (inferred from genus)
  • Worker: Size data unavailable, typical Temnothorax workers are 2-4mm (inferred from genus)
  • Colony: Unknown, typical Temnothorax colonies reach up to 500 workers (inferred from genus)
  • Growth: Moderate, expected based on genus patterns
  • Development: Not documented, typical Temnothorax is 6-10 weeks at optimal temperature (inferred from genus) (All timing is estimated from genus-level data. No species-specific studies have been done.)
• Antkeeping:
  • Temperature: Room temperature (18-24°C) is suitable. Aim for 20-22°C for steady activity. No exact data exists, these are general recommendations for temperate small ants.
  • Humidity: Keep the nest substrate slightly moist but not wet. Provide a humidity gradient with one damp area and the rest dry. These ants come from a mountainous region with good drainage.
  • Diapause: Yes, almost certainly. As a temperate Caucasus species, they need a winter rest period. Gradually lower temperature to 10-15°C for 2-3 months in winter (inferred from geographic range).
  • Nesting: Small, dark cavities suit them best. Test tubes, Y-tong nests, or small plaster formicaria with narrow chambers are ideal. Avoid large open spaces.
• Behavior: Peaceful and non-aggressive. Workers will flee rather than fight. Their primary defense is fleeing, but they have a modified stinger used to smear venom onto attackers (not painful to humans). Their tiny size makes them excellent escape artists, use fine mesh (0.5mm or smaller) on all ventilation and tight seals on connections.
• Common Issues: escape prevention is critical due to their very small size, use fine mesh and tight-fitting lids, limited species-specific information means you're mostly working from guesswork based on related ants, test tube setups can dry out quickly, so check moisture levels weekly, winter diapause is almost certainly needed, skipping it may harm the colony (inferred from habitat)

Housing and Nest Setup

Use a standard test tube with a water reservoir (fill one-third with water, plug with cotton, leave the rest as the nesting chamber). This mimics the small cavities they occupy in the wild. For larger colonies, switch to a small Y-tong (AAC) nest with narrow chambers scaled to their tiny workers. Avoid overly large chambers, they feel more secure in tight, dark spaces. A small outworld (feeding area) is fine. Because their natural nesting preferences are not documented, this setup is based on typical Temnothorax habits.

Feeding and Diet

Offer a mix of small protein prey (fruit flies, tiny crickets, or pieces of mealworm) 2-3 times per week, plus a constant supply of sugar water or honey water. Remove uneaten prey after 24 hours to prevent mold. No species-specific dietary data exists, so follow general small-ant feeding guidelines.

Temperature and Seasonal Care

Keep the nest at 20-22°C for steady activity and brood development. Room temperature (18-24°C) is usually fine. In autumn, gradually reduce temperature to 10-15°C for a winter diapause of 2-3 months. This is inferred from the species' temperate Caucasus origin. Do not skip the rest period, it likely regulates the colony's reproductive cycle. Avoid temperatures above 28°C or below 15°C outside of diapause.

Behavior and Handling

Workers are active foragers and will flee rather than fight. They have a modified stinger for smearing venom (subfamily Myrmicinae, tribe Crematogastrini). This is not painful to humans. The main challenge is their tiny size, they can escape through gaps smaller than 1mm. Use fluon barriers on test tube rims, fine mesh on all vents, and seal connections with Vaseline or tight tape. Overfeeding or poor ventilation can lead to mold, which is a bigger issue for small colonies.
