Camponotus inaequalis

Camponotus inaequalis - "Ant"

Camponotus inaequalis is a medium to large carpenter ant species native to Cuba, the Bahamas, southern Florida, and into Mexico. Workers are strongly polymorphic, meaning they come in distinct sizes, majors measure 9-11mm while minors are smaller at 6-7mm. Queens reach 10-11mm. The coloration is typically ferruginous (rusty brown) with a darker head and black or dark brown abdomen. This species belongs to the maculatus species complex within the subgenus Tanaemyrmex, and was previously known as Camponotus inaequalis before being synonymized in 2017 [AntWiki].

This is a nocturnal carpenter ant that nests in wood, both decaying wood in natural settings and sometimes wooden structures in homes. They are super-generalist predators and foragers, active at night when they hunt for prey and gather resources. In Florida, they are one of the most common indoor pest ants, accounting for significant complaints about wood damage and nuisance activity ^[1][2].

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Native to Cuba, Bahamas, and southern Florida (north to Volusia County), with records in Mexico's Durango state. Found in tropical and subtropical habitats, often in coastal areas and islands. Nests in rotting wood, under stones, and in human structures ^[3][4][5][6].
• Colony Type: Monogyne, colonies have a single queen. The species has strongly polymorphic workers with distinct major and minor castes ^[7].
• Size & Growth:
  • Queen: 10-11mm [AntWiki]
  • Worker: Major: 9-11mm, Minor: 6-7mm [AntWiki]
  • Colony: Up to several thousand workers based on typical carpenter ant patterns
  • Growth: Moderate
  • Development: 6-8 weeks (estimated based on typical Camponotus development at optimal temperature) (Development time is temperature-dependent. Like other Camponotus species, expect nanitics (first workers) to emerge smaller than normal workers.)
• Antkeeping:
  • Temperature: Keep at 22-26°C. They are tropical/subtropical ants that prefer warmth but can tolerate typical room temperature. A gentle gradient with a heating cable on one side allows them to regulate temperature ^[1].
  • Humidity: Moderate to high humidity preferred. Carpenter ants naturally nest in wood which provides some moisture. Keep nest substrate moderately moist but not waterlogged. They are drawn to humid environments in Florida ^[1].
  • Diapause: No true diapause required, being a tropical/subtropical species, they do not need hibernation. However, they may reduce activity in cooler winter months if kept in unheated spaces.
  • Nesting: Y-tong (AAC) nests work well for carpenter ants, or plaster nests that allow for some moisture. They can also be kept in naturalistic setups with rotting wood pieces. Avoid completely dry conditions.
• Behavior: Nocturnal foragers, they become active at night when they search for food. Majors (larger workers) typically stay in the nest while minors forage, showing division of labor between castes ^[8]. They are not particularly aggressive but can bite if threatened, and their bites may cause pain or allergic reactions in sensitive individuals ^[1]. Escape prevention is important, while not tiny, they are agile and can climb smooth surfaces. Use fluon on test tube rims and ensure formicarium connections are secure.
• Common Issues: colonies may abandon nests if too dry, monitor humidity closely, escape risk, they can climb glass and smooth surfaces, seal all connections, overfeeding leads to mold, remove uneaten food promptly, nocturnal activity may surprise keepers, they become active when lights are off

Housing and Nest Setup

Camponotus inaequalis does well in Y-tong (AAC) nests or plaster nests that hold humidity well. As a carpenter ant, they naturally excavate wood, so providing them with wooden structures or soft materials they can chew through is appreciated. Test tube setups work for founding colonies, use a water reservoir tube for humidity and keep it in a dark, quiet location. Once the colony reaches 20-30 workers, you can move them to a formicarium. Ensure all connections between outworld and nest are sealed tightly, these ants can squeeze through small gaps and climb smooth surfaces effectively. ^[1][2]

Feeding and Diet

Like other carpenter ants, C. inaequalis is a generalist feeder. They accept protein sources like mealworms, crickets, and other insects. Sugar water, honey, or sugar syrup should be offered regularly, carpenter ants have a sweet tooth and will readily consume carbohydrates. In the wild, they are super-generalists that hunt prey, scavenge, and collect honeydew from aphids. Feed protein prey 2-3 times per week depending on colony size, and keep a sugar source available at all times. Remove uneaten prey within 24-48 hours to prevent mold. ^[1]

Temperature and Seasonal Care

This is a tropical/subtropical species from Cuba, Bahamas, and southern Florida. They prefer temperatures in the 22-26°C range. Being from warm climates, they do not require hibernation or true diapause. However, if your room temperature drops below 18°C in winter, you may notice reduced activity, this is normal and they will become active again when warmed. A heating cable or mat on one side of the nest creates a temperature gradient they can choose between. Avoid temperatures below 15°C for extended periods. ^[1][4]

Behavior and Colony Dynamics

C. inaequalis is strongly polymorphic, this means you have distinct major workers (soldiers) and minor workers. Research on the closely related C. tortuganus shows that minor workers do the foraging while major workers typically remain in the nest ^[8]. This species is nocturnal, becoming most active at night when they search for food. They are not aggressive toward keepers but can deliver a painful bite if handled roughly or threatened. Their bites may cause allergic reactions in sensitive individuals ^[1]. Colonies grow moderately, expect several months before the first workers (nanitics) appear, then steady growth over 1-2 years to reach mature colony size.

Nuptial Flights and Reproduction

In Florida, swarming (nuptial flights) occurs primarily in spring and early summer ^[2]. Alates (reproductives) are produced seasonally and will emerge when the colony is mature enough. If you keep a colony long-term, you may eventually see winged queens and males develop. After mating, new queens will dig chambers to found colonies claustrally, sealing themselves in and raising the first brood alone on stored energy reserves.
