Camponotus friedae

Camponotus friedae

Camponotus friedae is a polymorphic carpenter ant species native to East Asia, found across Taiwan, mainland China (Zhejiang and Fujian), and Japan's Nansei Islands ^[1]. Workers come in two distinct sizes: minor workers measure around 5mm while major workers (soldiers) are significantly larger at 7-9mm ^[1]. They have a striking appearance with a black head, brown mesosoma, antennae and legs, and a blackish-brown gaster (the rear body section) ^[1]. Their most distinctive feature is the abundance of long erect hairs covering the mesosoma, head vertex, petiole, and gaster, over 20 long hairs on the mesosoma alone ^[1]. Queens are substantial at 12-13mm and were first described from Taiwan in 1912 ^[2].

These ants nest in soil and under stones in forests, forest margins, and grasslands ^[1]. They are relatively rare in Japan but more commonly found in Taiwan and mainland China ^[1]. As with other Camponotus species, they are claustral founders, the queen seals herself inside a chamber and lives off her stored fat reserves until her first workers (nanitics) emerge. This is a moderately sized carpenter ant that does well in captivity when provided with appropriate nesting sites and stable conditions.

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Native to East Asia, Taiwan, mainland China (Zhejiang, Fujian), and Japan's Nansei Islands (Amami-oshima, Miyako) ^[1]. They inhabit forests, forest margins, and grasslands where they nest in soil and under stones ^[1].
• Colony Type: Likely monogyne (single queen colony) based on typical Camponotus patterns. Queens are claustral founders who seal themselves in to raise the first brood alone.
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: 12-13mm ^[2]
  • Worker: Minors ~5mm, majors 7-9mm ^[1]
  • Colony: Unknown but likely several hundred workers based on typical Camponotus colony sizes
  • Growth: Moderate, typical for Camponotus species
  • Development: 6-10 weeks based on typical Camponotus development patterns (Development time depends on temperature, warmer conditions within range accelerate development. Nanitics (first workers) are smaller than normal workers.)
• Antkeeping:
  • Temperature: Keep around 22-26°C. A gentle temperature gradient allows ants to regulate their own exposure to warmth.
  • Humidity: Moderate to high, they naturally nest in soil and under stones in forest environments. Keep the nest substrate consistently moist but not waterlogged, with some drier areas available.
  • Diapause: Likely requires a winter rest period (diapause) given their temperate Asian distribution. Reduce temperature to around 10-15°C for 2-3 months during winter.
  • Nesting: Provide soil-based or plaster nests that allow them to excavate or occupy pre-made chambers. Test tube setups work well for founding colonies. They accept both naturalistic setups with soil and artificial formicaria.
• Behavior: Generally calm and non-aggressive for a carpenter ant. Workers are moderately active foragers. Major workers can deliver a bite if threatened but are not particularly aggressive toward keepers. They are moderate escape artists, use standard barrier methods but they are not as prone to escaping as tiny species. They primarily forage for honeydew and small insects.
• Common Issues: colonies may fail if kept too dry, monitor substrate moisture regularly, winter diapause is important for long-term colony health, skipping hibernation can weaken colonies over time, major workers are large but can still escape through small gaps, use proper barriers, foundating queens are sensitive to disturbance, avoid checking the nest during claustral founding, slow initial growth is normal, don't overfeed or overheat in an attempt to speed development

Housing and Nest Setup

For founding colonies, a simple test tube setup works excellently. Fill a test tube with water and plug the wet end with cotton, leaving enough dry space for the queen to move into. Place the queen in the tube and keep it in darkness with moderate humidity. The queen will seal herself into a chamber and begin laying eggs. Once you have 10-20 workers, you can transition to a proper formicarium. Camponotus friedae does well in both naturalistic setups (with soil or excavation plaster) and artificial formicaria (acrylic or Y-tong nests). They prefer nests with multiple chambers connected by narrow passages. Ensure the nest provides darkness, these ants prefer to stay hidden in their chambers rather than in exposed foraging areas. ^[1]

Feeding and Diet

Like other carpenter ants, Camponotus friedae is omnivorous. They primarily consume honeydew (the sugary waste from aphids) in nature, along with small insects and other protein sources. In captivity, offer sugar water or honey as a constant energy source. For protein, provide small insects like fruit flies, small mealworms, or crickets. Feed protein 2-3 times per week, removing any uneaten prey after 24 hours. They do not require specialized diets, standard ant feeding protocols work well. Fresh water should always be available.

Temperature and Seasonal Care

Maintain temperatures between 22-26°C for optimal colony activity and brood development. A slight temperature gradient (warmer on one side of the nest) allows workers to regulate their exposure to heat. During summer, room temperature is often sufficient. In winter, these ants benefit from a diapause period, reduce temperatures to 10-15°C for 2-3 months. This mimics their natural seasonal cycle and helps maintain colony health long-term. Do not abruptly change temperatures, transition gradually over 1-2 weeks. Signs of proper diapause include reduced activity and workers clustering together for warmth.

Colony Growth and Development

After the queen seals herself in (claustral founding), she will lay eggs and tend to the brood without leaving the nest. She survives entirely on her stored fat reserves, this is why a well-fed, healthy queen with a plump abdomen is essential for successful founding. Eggs hatch into larvae, then pupate, and finally emerge as nanitics (first workers) after 6-10 weeks depending on temperature. These first workers are smaller than normal workers but immediately begin foraging to feed the colony. Subsequent broods develop faster as workers can care for the larvae. A healthy colony will grow steadily, reaching several hundred workers over 1-2 years under good conditions. ^[2]

Behavior and Handling

Camponotus friedae workers are relatively calm and not prone to biting unless severely threatened. Major workers can deliver a nip with their mandibles but this is rarely a concern for keepers. Workers are moderately active and will establish foraging trails when food is available. They are not aggressive toward each other and maintain organized colony structures. When cleaning or moving colonies, gently coax workers into the new setup rather than shaking or tipping the container. These ants are not skittish and can be observed during foraging without causing significant disturbance to the colony.
