Cataglyphis mauritanica

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to North Africa (Algeria, Morocco, Tunisia), found in mountain meadows and arid steppe habitats with sandy or stony soils ^[1][2].
• Colony Type: Polygynous (multiple-queen colonies) with 2-19 queens per colony (average ~7). Queens are brachypterous (short-winged) and cannot fly, they disperse on foot with workers during colony fission. The colony reproduces by budding, with new colonies forming about 30m from the natal nest ^[3][4][5].
• Size & Growth:
  • Queen: ~9-10mm (inferred from genus patterns, no specific measurement available)
  • Worker: ~8mm ^[1]
  • Colony: Up to 3000 workers ^[6]
  • Growth: Moderate
  • Development: 6-10 weeks (estimated based on related Cataglyphis species) (Development time is inferred from genus patterns, direct measurements not available for this specific species)
• Antkeeping:
  • Temperature: Keep nest at 25-32°C with a gradient. These are heat-tolerant desert ants that can survive up to 40°C. They use heat hardening, pre-exposure to 37°C before severe heat stress significantly improves survival at 45°C.
  • Humidity: Low to moderate, these are desert ants adapted to dry conditions. Keep nest substrate relatively dry with a small water chamber for drinking access.
  • Diapause: Unknown, no specific data available for this species. Based on North African origin, they may experience reduced activity in winter but true diapause requirements are unconfirmed.
  • Nesting: Use a dry, warm nest setup. Y-tong (AAC) or plaster nests work well. Provide a temperature gradient so workers can choose their preferred warmth. Avoid humid or damp nesting materials.
• Behavior: Cataglyphis mauritanica are active foragers that venture out in hot conditions when other ants hide. They are scavengers, collecting dead arthropods and occasionally plant material. Workers forage individually within about 22m of their nest, with most activity within 10m. They are not aggressive toward conspecifics, multiple colonies can forage near each other without conflict. As Formicinae ants, they can spray formic acid as defense when threatened. Escape risk is moderate due to their size, standard barriers work well.
• Common Issues: heat stress, while heat tolerant, extreme temperatures above 45°C can be fatal without prior heat hardening, humidity, too much moisture can kill these desert-adapted ants, small colony fragility, founding colonies and small colonies are vulnerable to stress, escape prevention, workers are active and will explore for exits, use standard barriers

Colony Structure and Reproduction

Cataglyphis mauritanica has one of the most unusual reproductive systems in the ant world. Colonies are polygynous, meaning they have multiple queens, typically 2-19 per colony, with an average of about 7. Queens are brachypterous, meaning they have short, non-functional wings and cannot fly. Instead of mating during nuptial flights, queens disperse on foot with groups of workers to found new colonies nearby through a process called dependent colony foundation (DCF) or budding. The new colony forms about 30 meters from the natal nest. This is fundamentally different from most ants that have flying queens. The species also practices social hybridogenesis: queens produce new queens through asexual reproduction (thelytokous parthenogenesis), while workers are produced through sexual reproduction between two genetically distinct lineages that coexist in the population ^[3][7][4][8].

Heat Tolerance and Foraging

These ants are thermal specialists adapted to survive extreme heat. Research shows they have 100% survival at 40°C and can survive 45°C if they undergo heat hardening first, a process where exposure to moderate heat (37°C) for 2 hours before severe heat stress (45°C) significantly improves survival from 45% to 65%. They use this to cope with the extreme temperatures in their North African habitat. Workers forage during the hottest parts of the day when other ants stay hidden. They are scavengers, collecting dead arthropods including Hymenoptera (27% of prey), Orthoptera (12%), Coleoptera (6%), Diptera (4%), Hemiptera (12%), and Araneae (3%). They also occasionally collect plant material. Foragers search within about 22 meters of the nest, with 60-70% of foraging activity within 10 meters ^[9][10].

Nest Preferences and Housing

In the wild, these ants nest in mountain meadows and arid steppe habitats with sandy or stony soils. They dig nests that extend about 7.6cm into the upper soil layer. For captive care, provide a warm, relatively dry nest. Y-tong (AAC) nests work well, as do plaster nests with a small water chamber for humidity control. Avoid humid or damp conditions, these are desert ants that prefer dry environments. Provide a temperature gradient within the nest (around 25-32°C) so workers can regulate their body temperature by moving between warmer and cooler areas. The outworld should be escape-proof but can be kept at room temperature ^[1][10].

Feeding and Diet

Cataglyphis mauritanica are primarily scavengers that collect dead arthropods. In captivity, offer small insects (fruit flies, small crickets, mealworms) and other protein sources. They will also accept sugar water or honey as an energy source. Feed protein 2-3 times per week, and provide a constant sugar source. Remove uneaten food after 24-48 hours to prevent mold. Their foraging style is individual, workers leave the nest alone and search for food, carrying it back individually rather than using recruitment pheromones ^[10][9].
