Aphaenogaster faureli

Aphaenogaster faureli

Aphaenogaster faureli is a small to medium-sized ant from the Aphaenogaster crocea group, found only in the mountains of northeastern Algeria ^[1][2]. Workers typically show the slender build and moderate size (around 4-6 mm) characteristic of the genus, with coloration likely similar to related crocea group species ^[3]. These ants inhabit Aleppo pine forests at elevations between 1250-1400 meters in the Aurès Mountains, where they nest in forest soil and rotting wood ^[3]. Originally described in 1969 from multiple mountain locations including Djebel Innoumar and Djebel Boutchaout, this species remains rare in collections and poorly studied in captivity ^[3]. Their high-elevation habitat in the Palearctic region means they experience distinct seasons with cold winters, making them a cool-temperate species quite different from lowland tropical ants ^[4].

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to Algeria, specifically the Aurès Mountains in pine forests at 1300-1400m elevation ^[4][5][3].
• Colony Type: Presumed single-queen (monogyne) based on typical Aphaenogaster patterns, though specific studies are lacking.
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 6-8 mm based on genus patterns ^[3].
  • Worker: Estimated 4-6 mm based on genus morphology ^[3].
  • Colony: Unknown, likely several hundred workers based on related species (inferred).
  • Growth: Moderate (inferred from temperate Aphaenogaster patterns).
  • Development: Estimated 8-12 weeks at 22°C (inferred from related temperate Aphaenogaster species). (Development timing is unconfirmed for this species, first workers (nanitics) may emerge slightly faster than subsequent brood.)
• Antkeeping:
  • Temperature: Keep at 20-22°C during the active season. Provide winter hibernation at 10-15°C for 3-4 months ^[4][3].
  • Humidity: Moderate humidity with good drainage. Think forest floor with leaf litter, not tropical swamp. Allow the nest to dry slightly between waterings ^[3].
  • Diapause: Yes, required. High elevation origin means they need cold winter rest ^[4][3].
  • Nesting: In nature they nest in soil and rotting wood under pine forests. In captivity, use Y-tong nests, plaster nests, or test tubes with moderate humidity and ventilation ^[3].
• Behavior: Active foragers typical of the genus, likely collecting seeds and small insects. Not particularly aggressive. Escape risk is moderate, standard barriers work for this size range ^[3].
• Common Issues: high elevation origin means they suffer in constant heat above 25°C, keep them cooler than tropical species., wild-caught colonies from Algeria may carry parasites or diseases not found in captive-bred stock., limited scientific data means captive care is experimental, be prepared to adjust conditions based on colony response., hibernation is mandatory, skipping winter rest will weaken or kill the colony.

Distribution and Natural Habitat

Aphaenogaster faureli is found only in Algeria, specifically in the Aurès Mountains of the northeastern part of the country ^[5][4]. The type specimens were collected from multiple mountain locations including Djebel Innoumar, Djebel Boutchaout, Djebel Titouguelt, and Djebel Chenntouf at elevations between 1250-1400 meters ^[3]. These sites are characterized by Aleppo pine (Pinus halepensis) forests, suggesting these ants prefer well-drained, forested mountain habitats rather than lowland desert or tropical conditions ^[3]. The region experiences a temperate climate with distinct seasons, warm summers but cold winters at these elevations, which explains their need for hibernation in captivity ^[4]. As a member of the crocea species group, they are distinct from the more widespread subterranea group found across Europe ^[1][2].

Colony Founding and Structure

Specific founding behavior has not been documented for Aphaenogaster faureli, but based on typical patterns for the genus, queens likely practice claustral founding, meaning the queen seals herself in a chamber and lives entirely on stored body fat until her first workers hatch ^[3]. Most Aphaenogaster species are monogyne, meaning colonies contain just one queen, though this specific detail is unconfirmed for A. faureli. If you obtain a founding queen, house her in a standard test tube setup with a water reservoir and cotton plug. Keep her undisturbed in a dark, quiet place at moderate temperatures (around 20-22°C) during the founding phase.

Temperature and Hibernation

Temperature management is critical for this species. Coming from mountain habitats at 1300-1400 meters, they are adapted to cooler conditions than lowland ants ^[4][3]. During the active season (spring through autumn), maintain them at 20-22°C. Avoid letting them overheat above 25°C for extended periods. For winter care, they require a true hibernation period (also called diapause) of 3-4 months at 10-15°C ^[3]. You can achieve this by moving the colony to an unheated room, garage, or refrigerator set to the appropriate temperature. Ensure the nest does not dry out completely during this rest period, but also avoid excessive moisture that could cause mold in cold conditions.

Feeding and Diet

Like other Aphaenogaster species, A. faureli are omnivorous and likely practice seed harvesting (myrmecochory) as well as predation on small insects ^[3]. In captivity, offer a varied diet including small seeds such as millet, chia, or poppy seeds, which they may store in their nest chambers. For protein, provide small live insects appropriate to their size, fruit flies (Drosophila), small springtails, or pinhead crickets work well. You can also offer sugar water or honey water in a small test tube or on a cotton ball for carbohydrates. Remove uneaten food promptly to prevent mold growth, especially given their moderate humidity requirements.

Housing and Nest Requirements

In nature, these ants nest in soil and rotting wood in pine forests ^[3]. For captive colonies, standard ant-keeping setups work well. Start founding queens in test tubes with water reservoirs. Once the colony reaches 20-50 workers, move them to a small formicarium, Y-tong (autoclaved aerated concrete) or plaster nests both work well. Provide moderate humidity but ensure good ventilation to prevent mold. The nest should have both damp and slightly drier areas so the ants can choose their preferred microclimate. For the outworld, use a standard container with a barrier of Fluon or talcum powder to prevent escapes, though at 4-6 mm they are not the most escape-prone species if barriers are properly applied.
