Camponotus quadrisectus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to the Philippines, Borneo, Malaysia (Peninsula and Sarawak), and Indonesia (Sumatra). Found in tropical forest habitats where they nest in rotting wood, under bark, and in soil cavities ^[1][2][3].
• Colony Type: Likely monogyne (single queen colonies) based on typical Camponotus patterns, though this is not explicitly confirmed for this species.
• Size & Growth:
  • Queen: Approximately 14-15mm (originally described as 7 lines in length) ^[4]
  • Worker: 6-12mm (major and minor workers)
  • Colony: Up to several thousand workers at maturity, typical for Camponotus
  • Growth: Moderate
  • Development: 8-12 weeks at optimal temperature (typical for Camponotus in tropical conditions) (Development is temperature-dependent, warmer conditions within safe range accelerate development. Nanitics (first workers) are smaller than mature workers.)
• Antkeeping:
  • Temperature: Keep at 24-28°C for optimal development. This is a tropical species that prefers warm conditions. A slight gradient allowing workers to self-regulate is beneficial.
  • Humidity: Moderate to high humidity (60-80%). These ants come from humid tropical environments and need moisture, but avoid waterlogging the nest. Provide a water source.
  • Diapause: Not required. As a tropical species, they do not need hibernation.
  • Nesting: In captivity, they do well in Y-tong (AAC), plaster, or soil nests. Provide nesting chambers scaled to colony size. They prefer dark, secure spaces. A foraging area should allow them to hunt and forage freely.
• Behavior: Generally calm and non-aggressive for a large ant species. Workers are active foragers, primarily at night (nocturnal tendency). They are not particularly defensive but will bite if threatened. Escape risk is moderate, their larger size makes them easier to contain than tiny ants, but they are strong and can push through loose connections. They communicate through chemical trails and will recruit nestmates to food sources.
• Common Issues: colonies can stall if temperatures drop too low, keep warm, queens may die during founding if disturbed too much, provide quiet, dark space, large colonies need significant space, plan for expansion, mold can be an issue in humid setups, maintain proper ventilation, foraging workers may escape if the outworld is not properly sealed

Nest Preferences

In the wild, Camponotus quadrisectus nests in rotting wood, under loose bark, and in soil cavities in tropical forests. They prefer humid, shaded locations that stay relatively stable in temperature. For captive colonies, Y-tong (AAC) nests work excellently as they provide the dark, secure environment these ants prefer. Plaster nests with water channels can also work well, providing humidity control. The nesting area should be dark and sized appropriately, too large a space can stress founding colonies. As the colony grows, you can expand into additional formicarium sections. ^[2][1]

Feeding and Diet

Camponotus quadrisectus is a generalist feeder like most carpenter ants. In captivity, they readily accept sugar sources (honey, sugar water, maple syrup) which provides energy for active workers. Protein is essential for brood development, offer small insects like fruit flies, small crickets, mealworms, or frozen bloodworms. They are nocturnal foragers, so offering food in the evening often yields better results. A constant sugar source plus protein 2-3 times per week works well for established colonies. Remove uneaten prey after 24-48 hours to prevent mold issues.

Temperature and Care

As a tropical species from Southeast Asia, Camponotus quadrisectus thrives at warmer temperatures. Keep the nest area at 24-28°C for optimal brood development. Temperatures below 22°C can slow development significantly, and prolonged cold can be harmful. A heating cable on one side of the nest creates a gradient allowing workers to self-regulate. Place the heating on top of the nest, not underneath, to avoid drying out the substrate. Room temperature within this range is acceptable without additional heating. They do not require hibernation, this is a year-round active species.

Defense and Health

This is a relatively calm species for a large carpenter ant. Workers are not particularly aggressive and will typically flee rather than fight when disturbed. However, they have a powerful bite if cornered. They are primarily nocturnal, with most foraging activity occurring at night. Workers communicate through chemical pheromones and will form recruitment trails to good food sources. The mandibular glands produce antibiotic secretions including m-cresol and other antimicrobial compounds that help protect the colony from pathogens ^[5][6]. This is why these ants can thrive in humid environments that would be risky for other species. They are moderate escape artists, larger than most ants but strong enough to find gaps, so ensure all connections are secure.
