Camponotus fellah

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to the Middle East and North Africa, found in Egypt, Israel, Jordan, Iraq, Iran, Kuwait, Lebanon, Oman, Saudi Arabia, Syria, Turkey, and Yemen ^[1][2]. In Iran, specimens are collected mostly on ground-level habitats in moderate rainfall and montane areas, with one desert collection ^[7]. The species prefers warm, arid to semi-arid climates.
• Colony Type: Monogyne (single-queen) colonies. Colonies can become very large and polydomous, occupying multiple connected nests near bushes where they tend aphids ^[8]. Queens mate only once, and all workers are full sisters ^[9].
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements provided in research context.
  • Worker: Minor workers: under 8 mm, major workers: 7.8-17.2 mm total length ^[3][4]
  • Colony: Up to 1000+ workers in laboratory colonies, with wild colonies being very populous and polydomous ^[10][8]
  • Growth: Moderate
  • Development: Unknown, no specific data provided in research context. (Workers transition from nursing to foraging around 4 months old. Development is temperature-dependent, with optimal conditions around 25-30°C.)
• Antkeeping:
  • Temperature: Keep colonies at 25-30°C. Research colonies thrived at 25±3°C with 70±20% humidity ^[10] or at 27°C with 65% humidity ^[11].
  • Humidity: Maintain moderate humidity, around 65% relative humidity as in research conditions ^[11]. Provide a water source always available.
  • Diapause: No, this species is from warm climates and does not require hibernation.
  • Nesting: In nature, they nest in soil and under stones, forming polydomous colonies ^[4]. In captivity, they do well in Y-tong (AAC) nests, plaster nests, or naturalistic setups with soil substrate. Provide dark, secure nesting areas with multiple chambers.
• Behavior: Mostly nocturnal in the wild ^[10]. Not aggressive toward humans, they can bite but lack a functional sting. Workers tend to forage alone but may use group recruitment for major food discoveries ^[10]. They have excellent olfactory memory and can learn to discriminate odors quickly ^[10]. Escape risk is moderate, larger workers cannot escape typical gaps, but small gaps should be avoided.
• Common Issues: social isolation stress, isolated workers experience increased aggression from nestmates after 20+ days and have shortened lifespans due to oxidative stress ^[5][3]. keep colony transfers gentle and avoid isolating workers., endosymbiont dependence, colonies harbor Blochmannia bacteria essential for growth and immunity. antibiotic treatment severely reduces larvae production and worker numbers ^[13]. avoid antibiotics unless absolutely necessary., queen loss is terminal, as a monogyne species, colony death is inevitable once the queen dies. workers cannot replace her., cold sensitivity, being from warm climates, they are sensitive to temperatures below 20°C. keep them warm year-round., overfeeding mold, their preference for sugary foods can lead to mold issues if excess food is not removed promptly.

Housing and Nest Setup

Camponotus fellah does well in a variety of nest types. Y-tong (AAC) nests work excellently, the porous material helps maintain appropriate humidity while providing dark chambers. Plaster nests are another good option, as they hold moisture well. For a naturalistic approach, use a soil-filled setup with flat stones or pieces of wood as nesting surfaces. The key is providing dark, secure chambers that mimic the underground nests they form in the wild. Because they are polydomous in nature, you can connect multiple formicaria with tubing if your colony grows very large. Ensure the outworld is spacious enough for their nocturnal foraging activities. Use a test tube setup for founding colonies, a simple test tube with a water reservoir works well for the claustral founding phase. ^[4]

Feeding and Diet

These ants are omnivorous with a strong preference for sugary liquids. In the laboratory, they readily accept 20% sugar water, honey, and protein sources like tuna, mealworms, and eggs ^[11][10]. Feed sugar water or honey constantly, this should be available at all times in the foraging area. Protein should be offered 2-3 times per week, especially for colonies with brood. Dead mealworms, small crickets, or commercial ant protein gels work well. They are nocturnal foragers, so place food in the evening and remove any uneaten portions after 24 hours to prevent mold.

Temperature and Seasonal Care

Maintain temperatures between 25-30°C for optimal colony health and development. Research colonies thrive at 27°C with 65% humidity ^[11] or at 25±3°C with 70±20% humidity ^[10]. They can tolerate slightly higher temperatures but avoid temperatures below 20°C for extended periods. Being from warm climates, they lack cold tolerance. No true diapause is required.

Social Structure and Colony Dynamics

Colonies are monogyne (single queen) and can grow very large with multiple connected nests (polydomous) ^[12][8]. The queen mates only once, so all workers are full sisters ^[9]. Nestmate recognition is based on cuticular hydrocarbons that must be continuously exchanged through trophallaxis and grooming to maintain the colony 'gestalt' odor ^[5][6]. Workers isolated for more than 20 days develop different hydrocarbon profiles and are attacked by their former nestmates ^[5]. The queen influences colony behavior by reducing worker social motivation, queenless workers are more tolerant of foreign ants ^[12]. Workers live approximately one year, with younger workers performing nursing duties and older workers transitioning to foraging ^[3].

Health and Symbionts

Camponotus fellah harbors an essential bacterial endosymbiont called Blochmannia located in bacteriocytes in the midgut and in queen oocytes ^[13][8]. This bacteria is crucial for colony growth, antibiotic treatment that reduces Blochmannia by 75% causes significantly fewer larvae and workers after 3 months ^[13]. The symbiont also aids immune defense: colonies with more Blochmannia have stronger encapsulation responses ^[13]. Antibiotics should be avoided unless absolutely necessary.

Behavior and Foraging

C. fellah is primarily nocturnal in the wild ^[10]. They do not use obvious trail pheromones, workers tend to forage individually, though they may use group recruitment for significant food discoveries ^[10]. They have excellent olfactory learning abilities and can form strong odor-food associations within just a few visits, with memory lasting at least 72 hours ^[10]. In the nest, they use chemical cues to organize space, different areas have different hydrocarbon signatures ^[14]. They are not aggressive toward keepers and lack a significant sting, making them safe to handle.
