🌿 Live Asian Marauder Ant Colony for Observation & Keeping: Carebara diversa is one of Asia's most spectacular mass-raiding ants, combining extreme worker polymorphism, enormous food demand, highly organized swarm foraging, and the potential to develop into a very large mature colony. International shipping is available to supported destinations via Air Express. Colony size and queen count follow the selected variant; worker counts refer to live workers unless otherwise stated.
⚠️ Critical Pre-Purchase Note: Carebara diversa is not difficult because of one unusual trick; it is difficult because a successful colony combines very small escape-prone workers, continuously humid brood chambers, high food turnover, rapid recruitment, heavy waste production, and potentially enormous long-term space requirements. This species is best suited to experienced keepers who can maintain stable warmth, reliable hydration, frequent feeding, excellent ventilation, and expandable housing.
Origin & Queen-Count Note: Chinese and other Asian captive stocks can differ in coloration, worker proportions, queen number, growth behavior, and colony compatibility. Multiple-queen colonies are well established in Chinese and Taiwanese keeping and sourcing experience, but unrelated colonies or queens should never be merged at random. The actual queen count supplied by AntNook follows the selected variant.
Carebara diversa (Jerdon, 1851), formerly known as Pheidologeton diversus, is the classic Asian Marauder Ant. It belongs to the subfamily Myrmicinae and is famous for converging on an army-ant-like style of mass foraging despite not being a true army ant.
The species is widespread across the Indomalayan region and is also a genuine part of the Chinese ant fauna. Current Chinese taxonomic records include populations from Fujian, Guangdong, Guangxi, Hainan, Hong Kong, Macao, Taiwan, and Yunnan. Recognized regional forms such as C. diversa draco and C. diversa laotina are also recorded from parts of southern China, making locality information especially valuable when comparing colonies.
Not a Technical “Supercolony” Claim: Mature colonies can become enormous, but AntNook avoids using “supercolony” as a scientific synonym for “very large colony.” Published syntheses commonly describe mature colonies in the tens of thousands, with broader trait compilations reporting substantially larger colonies. Chinese and Taiwanese keeper observations also document very large multi-queen colonies. Exact maximum size varies with locality, queen number, food availability, climate, and available nesting space.
Extreme Continuous Polymorphism: The worker population is not divided into only three rigid sizes. Instead, C. diversa shows a remarkable continuous series from tiny minors through progressively larger intermediate workers to massive majors and supermajors. This continuous polymorphism is one of the defining characters of the former Pheidologeton lineage.
Minor Workers: The smallest workers are approximately 2–3 mm and make up the numerical majority of a mature colony. They perform much of the brood care, trail traffic, food transport, nest maintenance, queen attendance, and mass recruitment.
Intermediate Workers: Workers of progressively larger size bridge the gap between minors and the biggest majors. Their tasks overlap rather than forming one fixed “media caste,” and larger intermediates become increasingly important in transport, food processing, trail work, and cooperative predation.
Majors & Supermajors: The largest workers develop disproportionately massive heads and powerful mandibles. Depending on geographic stock and measurement method, the largest majors are commonly reported around 16–20 mm. They are especially effective at cutting tough food, attacking or restraining large prey, clearing obstacles, and processing material for smaller nestmates.
Queens: Queens are very large, typically around 20–25 mm, with a body plan dramatically different from the smallest workers. This size contrast between a tiny minor and a full-sized queen or supermajor is one of the most striking examples of caste scaling among commonly kept ants.
Carebara diversa is not restricted to pristine rainforest. Field records include forest edges, secondary woodland, gardens, disturbed vegetation, agricultural landscapes, and urban or semi-urban environments. Colonies usually nest in soil or other protected ground-level sites and can establish extensive underground systems.
True Group Hunting: The army-ant comparison is not marketing exaggeration. Classic behavioral research demonstrated genuine group hunting in C. diversa: workers search and advance as coordinated raiding groups rather than relying only on solitary scouts followed by simple recruitment.
Long-Term Trunk Trails: Mature colonies can construct persistent trunk trails extending extraordinary distances from the nest. Published syntheses describe trail systems reaching roughly 100 m, sometimes protected by soil-built walls or roofed sections that function almost like extensions of the nest.
Massive Foraging Columns: Large colonies can mobilize thousands of workers simultaneously. Published accounts describe foraging columns containing around 10,000 workers and swarm fronts expanding into broad fan-shaped raids several metres across. These trails may remain active for long periods and can operate both day and night.
Division of Labor by Body Size: The largest workers are not simply “soldiers.” Body size changes what each worker can do. Small workers excel at mass transport, brood care, traffic, and recruitment, while larger workers become increasingly important in prey capture, cutting, trail clearing, carrying, seed processing, and food storage. The result is a flexible size-based labor system rather than three perfectly separated job categories.
Generalist Foraging: Unlike obligate specialist predators, C. diversa exploits a broad range of resources. Wild colonies take arthropods and carrion but can also harvest plant material including seeds, nuts, fruits, and other energy-rich foods.
Winged Queens & Nuptial Flights: Unlike true army ants with highly specialized wingless queens, C. diversa produces large winged reproductive females. Queens participate in nuptial flights and are capable of founding new colonies, another important reason this species should be described as army-ant-like rather than as a true army ant.
Multiple-Queen Chinese Stock: Multi-queen colonies are repeatedly documented in Chinese and Taiwanese captive, breeder, and sourcing experience, including established colonies containing several reproductive queens. Because published species-wide studies of queen structure remain much thinner than the husbandry record, AntNook treats queen number as a stock- and locality-specific trait and states it according to the actual colony being sold.
Do Not Randomly Merge Colonies: The fact that some Chinese stocks can maintain or accept multiple queens does not mean that every unrelated queen or colony is automatically compatible. Preserve the original colony unit unless compatibility is already known for that source population.
Growth Potential: Once a colony is established with a strong brood reserve, adequate worker force, stable heat, and abundant food, population growth can accelerate dramatically. However, young or recently transported colonies can also decline quickly if worker turnover exceeds the production of replacement minors.
Nest Type: Soil-based setups, gypsum, plaster, Ytong/AAC, well-hydrated test-tube systems, or appropriately designed modular nests can all work. The important features are reliable hydration, excellent ventilation, very small escape gaps, and the ability to expand the nest gradually as worker numbers increase.
Modular Expansion: Do not give a small colony an enormous empty nest immediately. Expand chamber space in stages. A modular system is useful because established colonies can grow rapidly and may eventually require several connected nest units and a much larger outworld.
Temperature: Approximately 25–28°C (77–82°F) is a strong practical starting range for most Chinese and Southeast Asian captive stock. Slightly warmer local zones can be offered, but avoid heating the entire system aggressively. Always provide a cooler retreat so the colony can regulate its own position.
Humidity: The queen and brood zone must remain reliably humid. Approximately 70–85% RH can be used as a practical reference for the humid nest zone, but the entire enclosure should not be kept saturated. A moisture gradient with a humid core and comparatively drier, well-ventilated peripheral areas is safer than one fixed humidity value everywhere.
Ventilation: High humidity combined with heavy feeding makes stagnant setups dangerous. Provide strong passive ventilation without allowing the brood chambers to dry out. Mold, decomposing prey, and mite outbreaks become much more difficult to control once a colony is large.
Foraging Area: Provide generous horizontal space for trail formation, recruitment, food processing, and waste management. Large colonies can mobilize enormous numbers of tiny workers in minutes.
Escape Security: The smallest minors are only a few millimetres long and can exploit gaps that would contain most large ants. Check lids, mesh, tubing, cable openings, nest joints, and anti-escape barriers carefully. Containment should be designed around the smallest worker, not the largest major.
Seasonality: Tropical and subtropical stock should not be given a conventional winter diapause. Keep the colony warm and functional year-round. Some populations may slow when temperatures fall, but deliberate cold hibernation is not recommended.
High Food Demand: A growing C. diversa colony can process an extraordinary amount of food. Feeding frequency must be based on worker number, brood volume, and how quickly the colony removes food rather than on one fixed universal schedule.
Animal Protein: Offer clean feeder insects such as roaches, crickets, mealworms, flies, silkworm pieces, termites, or other appropriately sized arthropods. Freshly killed or cut prey is completely suitable and is safer than large defensive live prey.
Plant-Based Foods: Mature colonies are not strict carnivores. Small seeds, crushed nuts, grains, and occasional pieces of suitable fruit can be offered alongside animal prey. Acceptance can vary by colony, season, and geographic stock.
Carbohydrates: Sugar water or diluted honey water can be offered as a clean liquid energy source, but it should complement rather than replace the colony's broader diet.
Feeding Frequency: Small colonies may be fed according to consumption every 1–2 days, while large colonies with heavy brood can require fresh food daily or even more frequently. Chinese long-term keeping records show that fast-growing colonies can visibly lose worker mass when food supply is interrupted, so consistent feeding is more important than following a minimalist schedule.
Waste Control: Remove spoiled food promptly. Large colonies may drag prey deep into the nest or bury leftovers, which can create hidden mold and mite problems. A cleanable outworld and comparatively dry waste zone are extremely useful.
Water: Fresh drinking water must remain available in addition to nest hydration and sugar solution.
Worker Turnover: Experienced keepers consistently report unusually rapid turnover among the smallest workers. Exact minor-worker lifespan has not been well quantified in controlled species-level studies, so AntNook does not present a fixed “3-week” or “7-week” lifespan as scientific fact. The practical lesson is more important: a healthy colony needs a large brood reserve continuously producing replacement workers.
Watch the Brood, Not Only the Worker Count: A colony with thousands of workers but little brood can be less secure than a smaller colony with a queen actively producing and a dense reserve of eggs, larvae, and pupae. Brood volume is one of the most useful indicators of future colony stability.
Transport Recovery: Do not force a newly arrived colony into a large nest immediately. Complete the required continuous unboxing video first, then provide warmth, hydration, food, and a dark retreat. Let the ants choose when to move unless the transport container presents an immediate safety problem.
Do Not Normalize Arrival Losses: Worker mortality after shipping should not be advertised as “normal” or automatically dismissed. Evaluate the queen or queens, brood condition, worker activity, temperature, hydration, and the current AntNook Live Arrival Guarantee together.
Mites & Mold: This species combines exactly the conditions that favor husbandry problems: warmth, humidity, protein-rich food, and large amounts of waste. Prevention is easier than rescue. Use clean feeder insects, strong ventilation, removable food dishes, dry waste areas, and regular visual checks.
Long-Term Space Commitment: The impressive growth of C. diversa is also its biggest management challenge. Before purchasing a large colony, plan where additional nest modules, larger outworlds, heating, hydration, and escape barriers will go months later—not just where the starter colony will fit today.
