Temnothorax anacanthus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to Morocco, from the Atlantic coast to the Atlas Mountains up to Ifrane ^[2]. Found in open matorral (shrubland) habitat, nesting under stones in areas with Calycotome villosa and Pistacia lentiscus vegetation, typically lacking ground litter ^[1].
• Colony Type: Likely monogyne (single-queen colonies) based on genus patterns, but this is unconfirmed from direct study ^[1].
• Size & Growth:
  • Queen: size data unavailable, inferred from Temnothorax genus, approximately 3-5mm
  • Worker: size data unavailable, inferred from Temnothorax genus, approximately 2-4mm
  • Colony: Unknown
  • Growth: Unknown
  • Development: Unknown (No published data on development time for this species.)
• Antkeeping:
  • Temperature: No specific data. Based on Moroccan habitat, aim for 20-25°C during the active season and provide a gradient so ants can self-regulate. If the colony slows down in winter, provide a cooler period at 10-15°C.
  • Humidity: They nest in dry shrubland, keep the nest substrate mostly dry with a small moist area to create a gradient. Avoid constant wetness.
  • Diapause: Unconfirmed but likely needed due to temperate origin. If the colony reduces activity in winter, provide a cooling period (10-15°C) for a few months.
  • Nesting: Naturalistic setups with flat stones or soil, or Y-tong (AAC)/plaster nests with small chambers work well, reflecting their natural nesting under stones ^[1].
• Behavior: Peaceful and not aggressive. Defense mechanism is smearing venom from a modified stinger, typical of the Crematogastrini tribe. Escape prevention is critical due to their small size, they can slip through standard test tube cotton.
• Common Issues: escape prevention is critical due to their tiny size, they can squeeze through standard test tube cotton, colonies may suffer if humidity is too high, their natural habitat is relatively dry, winter dormancy requirements are unconfirmed, monitor colony and provide a cool rest if they slow down, wild-caught colonies may carry parasites that can decimate captive populations, sparse care information means keepers must be prepared to adapt conditions based on observation

Housing and Nest Setup

Temnothorax anacanthus is a small species that needs appropriately scaled housing. In the wild, they nest under stones in relatively dry shrubland, so your setup should mimic these conditions ^[1]. A Y-tong (AAC) nest with narrow chambers works well, as does a plaster nest or a naturalistic setup with flat stones laid on soil. The chambers should be tight, these tiny ants feel exposed in large open spaces. Test tubes can work for founding colonies but may need modification to prevent escapes due to their small size. Use a water tower or hydration system that allows you to control moisture without flooding the colony. A small outworld area for foraging completes the setup ^[1].

Feeding and Diet

Like many small omnivorous ants, this species likely accepts a variety of foods. Offer sugar water or honey water as a constant energy source. For protein, provide small live prey such as fruit flies, pinhead crickets, or mealworm pieces. No specific dietary preferences are documented for this species, so observe your colony and adjust. Feed small amounts 2-3 times per week, removing uneaten prey after 24 hours to prevent mold.

Temperature and Seasonal Care

No published temperature requirements exist for this species. Based on the Mediterranean climate of Morocco, keep the colony at typical room temperature (20-25°C) during the active season. A temperature gradient is ideal, place a heating cable on one side so workers can move between warmer and cooler areas. If the colony becomes inactive in winter, reduce temperatures to 10-15°C for a few months to provide a natural rest period. Do not feed during diapause and minimize disturbance. Return to normal temperatures gradually in spring.

Colony Development and Growth

There is no specific data on colony development or growth rate for this species. Based on general patterns in Temnothorax, a newly mated queen will likely seal herself in a small chamber and lay eggs, raising the first brood on her body reserves. The colony probably grows slowly, but timelines and mature sizes are unknown. Patience and adaptation to observed behavior are key.

Behavior and Observation

Temnothorax anacanthus is a peaceful species that relies on escape or smearing venom rather than stinging, typical of its tribe (Crematogastrini). Workers are active foragers that will venture out to collect food. They are not aggressive and may feign death when threatened. Their small size makes escape prevention a priority. They do best with minimal disturbance during the founding phase.
