Aphaenogaster dejeani

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to the Anti-Atlas and Sarhro mountain ranges of southern Morocco ^[3][4]. Found at elevations including Jebel Kouali (1726 m) in the Horst chain ^[1].
• Colony Type: Colony structure unconfirmed, specific data on queen number is unavailable for this species.
• Size & Growth:
  • Queen: size data unavailable, inferred from Aphaenogaster genus (~6-8 mm)
  • Worker: size data unavailable, inferred from Aphaenogaster genus (~4-6 mm)
  • Colony: Unknown, likely moderate based on genus patterns.
  • Growth: Moderate
  • Development: 8-12 weeks (inferred from related Aphaenogaster species at 24°C) (Specific development data unconfirmed for this species.)
• Antkeeping:
  • Temperature: Keep at 20-25°C during active season with cooler nights, provide winter cooling to 10-15°C for 2-3 months based on extratropical mountain habitat ^[4].
  • Humidity: Moderate humidity, nest substrate should feel damp but not waterlogged, with some dry areas available.
  • Diapause: Likely yes, winter rest period recommended based on extratropical mountain distribution ^[4].
  • Nesting: Under stones and in rotting wood in nature, use Y-tong, plaster, or naturalistic nests with soil substrate.
• Behavior: Moderate activity levels typical of the genus, scavenging foragers that recruit to food. Not particularly aggressive but will defend brood. Escape risk is moderate due to medium worker size.
• Common Issues: limited availability in the hobby due to endemic Moroccan distribution., mountain climate requirements need careful temperature management including winter cooling., desiccation risk if kept too dry, mountain habitats retain moisture., slow growth rates if kept below optimal temperature.

Nest Preferences

In their native Moroccan mountains, Aphaenogaster dejeani nests under stones and in rotting wood ^[3]. They prefer tight spaces with moderate humidity. In captivity, a Y-tong or plaster nest works well with a soil or sand substrate layer. You can also use a naturalistic setup with flat stones buried slightly in substrate to simulate their stone-dwelling habits. Keep one side of the nest slightly moister than the other so the colony can choose their preferred humidity.

Temperature and Seasonal Care

Coming from extratropical mountain regions at roughly 31°N latitude, these ants experience distinct seasons ^[4]. Keep the colony at 20-25°C during the active season, with a slight drop at night to 15-18°C to mimic mountain conditions. For winter care, gradually lower temperatures to 10-15°C for 2-3 months to simulate their natural diapause period. This winter rest helps maintain healthy colony cycles. Use a heating cable on one side of the nest if your room runs cool, but always provide a gradient so ants can self-regulate.

Feeding and Diet

Like other Aphaenogaster species, they are generalist scavengers and predators. Offer small insects such as fruit flies, pinhead crickets, or pieces of mealworm. They also accept sugar water or honey water. Feed protein twice weekly and keep a sugar source available constantly. Remove uneaten food within 24 hours to prevent mold in the humid nest environment they prefer.

Behavior and Temperament

These ants show typical Aphaenogaster behavior, moderately active foragers that use chemical trails to recruit nestmates to food finds. They are not particularly aggressive toward keepers but will defend their brood if disturbed. Workers are medium-sized enough that escape prevention is manageable with standard barriers, though you should still use tight-fitting lids and Fluon or baby powder barriers on outworld rims.
