Colony Life Cycle and Reproduction
Understanding the Colony Life Cycle and Reproduction of Carebara Diversa
Colony Structure and Queen’s Role:
Queen Dynamics: Within the Carebara diversa species, known as Queen Dynamics, the queen plays a vital role. She stands out due to her substantial size compared to other members of the colony and is primarily responsible for reproduction. After a single mating session, she retains the sperm to fertilize her eggs throughout her lifespan. Her size is quite remarkable, ranging from 22 to 25mm.
Polygyny: The species display polygyny, which means a single colony can host numerous queens, thereby boosting the colony's ability to withstand adversity and enhancing its growth prospects. In nature, some colonies have been observed to house up to 50 queens operating in unison.
Worker Roles: The worker roles are split into two categories - minor workers and major workers. The minors are tasked with caring for the offspring, whereas the majors protect the nest. This division of labour ensures an efficient and structured colony system.
Reproductive Strategies:
Swarming for Reproduction: The process of reproduction takes place through a swarm, where winged males and untouched queens venture out for mating. This often involves partners from various colonies to uphold genetic diversity.
Colony Expansion: After the mating process, a queen, now fertilised, sets up a fresh colony. This can sometimes result in colonies housing as many as 500,000 workers.
Subspecies and Adaptation:
Diversity Among Subspecies: Nine distinct subspecies of Carebara diversa, including Carebara diversa draco and Carebara diversa philippina, have been identified, each uniquely adapted to their specific environmental niche.
Nest Characteristics: Contrary to the temporary dwelling of army ants, the Carebara diversa develops enduring habitats, essential for the consistent growth and sustainability of their vast colonies.
A detailed study of the life cycle and breeding patterns of Carebara diversa reveals their intricate social structure and flexible survival methods. This makes them an intriguing subject for both hobbyists and scholars.
Keeping Carebara diversa in Formicarium
When keeping Carebara diversa in Formicarium, it's essential to replicate their natural conditions to ensure their health and well-being. Here are the key considerations:
Environmental Conditions:
Humidity: Maintain a humidity level of 60-80% in the arena and 70-90% inside the nest. This mimics their natural tropical environment, crucial for their survival.
Temperature: The arena should be kept between 22-35°C, while the nesting area should have a slightly narrower range of 27-33°C. These conditions help simulate the warm, humid conditions of their native habitats.
Nesting Materials: Use materials like sandy loam substrate or plaster of Paris. These materials provide the necessary insulation and moisture retention.
Initial Setup: Start with a test tube setup using cocopeat as the substrate, ideal for young colonies.
Transition to Larger Formicarium: Once the colony grows to about 80-100 workers, transfer them to a Natural Ant Farm. This provides more space and better humidity control.
Special Considerations:
Light Sensitivity: Carebara diversa may not be as sensitive to light as once thought; however, care should still be taken with lighting conditions.
Mite Infestations: Regularly check the live food you feed the ants for mites, as these can be common. Proper cleanliness and maintenance of the formicarium can help manage these pests.
Handling: Due to their fast growth and potential aggression, these ants are not recommended for children or beginner antkeepers. They require careful handling to avoid stress and disruption to the colony.
By adhering to these guidelines, enthusiasts and researchers can successfully maintain healthy Carebara diversa colonies in captivity, observing their fascinating behaviours and complex social structures.
Allow us to share some insights on how to care for these tiny beings in a controlled environment. These ants are extremely hostile and will confront anything that enters their surroundings.
Their bite can cause significant discomfort, however, they don't possess a sting. I discovered this through personal experience with a moderately sized major, approximately 12mm in size, which resulted in a laceration. So, refrain from attempting this!
Avoid being misled by numerous ant vendors who may attempt to sell you the Carebara Affinis in place of the Carebara Diversa. The size distinction between the queens of these two species is significant and can serve as an identifying characteristic. Specifically, queens of Carebara Diversa measure approximately 2.5 cm, whereas their Carebara Affinis counterparts are notably smaller, with a size of around 1.7 cm.
In 2019, I began with a single queen and a mere 50 petite workers sourced from Malaysia. Within a year, I nurtured this small group into a bustling colony of over 5000 workers ranging in size from 2mm to 8mm. Additionally, a handful of gigantic majors measuring about 15mm also emerged. However, the journey wasn't easy. The transformation from egg to worker ant typically requires 26-30 days, provided the ants are kept at an average temperature of 30 degrees Celsius. For the larger majors, the process is lengthier, approximately 45-50 days. The ant habitat has undergone numerous enhancements during this period. On an average day, the queen can produce around a hundred eggs.
About ant farms, I could inundate you with a plethora of details, but brevity is key here. The foundation should be a blend of sand and loam in equal proportions. Thoroughly mix it, next, portion it out into individual bags and freeze (-18 degrees C) for about a week to ten days. This process helps eliminate any potential contaminants or microbial life. Post this stage, each bag (around 500 grams) should be microwaved (at 800 Watts) for 3 minutes. Subsequently, open the bags and allow the mixture to cool down. And there you have it, you're all set to get started. If you're in a rush to accommodate your new Carebara diversa colony then you can buy the substrate from us.
I do not recommend using a heating mat for the ant farm but a 12-volt self-regulating heating cable powered up by a 5-volt transformer and of course, controlled by a digital multi-sensor thermoregulator with time setting option control, so you can set different temperatures during the daytime and overnight.
Now, we're onto the challenging bit. Arrange it in a way where 30% of the heat impacts the bottom, and the remaining 70% is distributed across the top third of the nest tank, within a soil filling no more than 100mm high. Before starting, ensure to coat the heating cable with PVA glue; this will be crucial for reinforcing the nest's structure later on. Utilise Natural Jute Thread for additional reinforcement when introducing the soil. Have you ever noticed the configuration of underfloor heating pipes? In the same fashion, position the jute thread every 25 mm, beginning at the first layer at 25mm, followed by 50mm and ultimately at 75mm. The gap between each thread is also 25mm – simple to remember. Bypassing this stage can lead to the nest's chambers potentially collapsing due to their substantial dimensions; hence, avoid making errors and inadvertently entombing the queen.
Adjust the temperature control to 27 degrees Celsius for the night hours and elevate it to 33 degrees Celsius throughout the day. Refrain from wetting the earth, but if a fog generator isn't available, mist the enclosure's walls several times daily. Aim to maintain an atmospheric moisture level ranging between 90 and 97% to ensure the substrate stays perfectly damp, providing an optimal environment for the sustained growth of these creatures. Use an Atomiser Mist Spray Bottle and moisturise the ant farm twice a day at least.
Maintaining a colony like this necessitates a vast quantity of food each day, and one must exercise extreme caution while disposing of the remaining food to avoid damaging the chambers of their nest. I found out that these creatures have a preference for deceased insects and can be provided with a diverse array of protein-heavy foodstuffs. This can include mealworms, crickets, and locusts, as well as uncooked chicken, tuna, and chia seeds on an occasional basis.
