Camponotus pseudolendus

Camponotus pseudolendus

Camponotus pseudolendus is a large Asian carpenter ant native to southern and southwestern China. Major workers reach an impressive 13.5-14.6mm in total length, making them one of the larger Camponotus species ^[1]. They belong to the subgenus Orthonotomyrmex and have very distinctive morphology: a completely dull body surface with abundant erect hairs (30-40 on the pronotum alone), relatively long pubescence, and a scape that extends about one-third its length beyond the head ^[1]. The mesosoma has a continuous arched dorsal profile, and the propodeum has nearly equal basal and declivity faces with a very steep declivity ^[1]. These ants are found in Sichuan and Yunnan provinces, typically in forested habitats.

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Camponotus pseudolendus is native to southern China, specifically Sichuan and Yunnan provinces. They inhabit forest environments in mountainous regions ^[2].
• Colony Type: Colony structure is unconfirmed for this species. Based on typical Camponotus patterns, they are likely single-queen (monogyne) colonies with claustral founding.
• Size & Growth:
  • Queen: Unknown, not described in available literature
  • Worker: Major workers: 13.51-14.59mm, minor workers would be significantly smaller ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Moderate, based on typical Camponotus development patterns
  • Development: Estimated 6-8 weeks at optimal temperature based on typical Camponotus genus patterns (Development time inferred from related Camponotus species, specific data for C. pseudolendus unavailable)
• Antkeeping:
  • Temperature: Keep at 22-26°C. Sichuan and Yunnan provinces experience warm summers, so a gentle heat gradient is beneficial. Room temperature within this range is acceptable.
  • Humidity: Moderate humidity around 50-60%. Provide a water source and keep the nest substrate slightly moist but not waterlogged. These are forest-dwelling ants, not desert species.
  • Diapause: Likely required. Based on the temperate climate of their native Sichuan/Yunnan habitat, provide a winter rest period of 2-3 months at 10-15°C.
  • Nesting: Use a spacious nest such as a Y-tong (AAC) formicarium or a large acrylic/plaster nest. As large carpenter ants, they need room for major workers and brood chambers. Avoid overly compact setups.
• Behavior: These are relatively calm carpenter ants with typical Camponotus temperament, not particularly aggressive but will defend if threatened. Major workers are robust and can deliver a mild sting if handled roughly. They are moderate foragers and will collect sugar sources and protein. Escape prevention is important due to their size, use standard barriers but they are not escape artists like tiny species. They are primarily nocturnal or crepuscular foragers.
• Common Issues: colonies may grow slowly initially, patience is required during the claustral founding phase, large size means they need spacious nests as colonies expand, winter diapause is likely essential for long-term colony health, skipping it may cause problems, wild-caught colonies may carry parasites that affect captive survival, test tube setups work for founding but colonies will need larger housing within 6-12 months

Housing and Nest Setup

Camponotus pseudolendus requires spacious housing due to the large size of major workers. For founding colonies, a standard test tube setup works well, use a tube with a water reservoir separated by a cotton plug, providing humidity without flooding. Once the colony reaches 20-30 workers, transition to a formicarium. Y-tong (AAC) nests work excellently for this species, or large acrylic nests with chambers sized appropriately for large ants. Avoid tiny setups, these ants need space to accommodate major workers that can exceed 14mm. Provide an outworld (foraging area) connected to the nest with tubing. The outworld should be large enough for feeding and waste management. ^[1]

Feeding and Diet

Like other Camponotus species, C. pseudolendus is omnivorous with a preference for sugar sources and protein. Offer honey water or sugar water as a constant energy source. For protein, provide insects such as mealworms, crickets, or other appropriately sized prey. Feed protein 2-3 times per week, adjusting based on colony size and consumption. Remove uneaten prey after 24-48 hours to prevent mold. These ants are foragers rather than aggressive hunters, so wounded or slow-moving prey is more readily accepted. Fresh fruit can occasionally be offered as a sugar source.

Temperature and Seasonal Care

Maintain temperatures between 22-26°C for optimal colony growth and brood development. A gentle heat gradient allows ants to self-regulate their temperature preferences. Place a heating cable on one side of the nest if room temperature falls below 22°C. During winter, provide a diapause period of 2-3 months at 10-15°C. This mimics the seasonal cycle of their native Sichuan/Yunnan habitat and is likely essential for long-term colony health and reproduction. Do not skip diapause as it may disrupt the colony's natural cycles and reduce lifespan or reproduction success.

Growth and Development

Major workers of C. pseudolendus reach an impressive 13.5-14.6mm, making them one of the larger Camponotus species ^[1]. The colony will produce both major and minor workers, majors develop from larger pupae and serve as specialized workers for defense and heavy food transport. Development from egg to first worker likely takes 6-8 weeks at optimal temperature, similar to other Camponotus species. The first workers (nanitics) will be smaller than mature majors but still relatively large. Growth rate is moderate, colonies may take 1-2 years to reach significant sizes under good conditions.

Behavior and Temperament

Camponotus pseudolendus displays typical carpenter ant behavior, they are generally calm and not prone to excessive aggression. Workers will investigate food sources and recruit nestmates through chemical trails. Major workers serve as soldiers and foragers, using their size advantage for tougher tasks. They are primarily nocturnal or crepuscular, so you may see more activity during evening hours. When threatened, they may raise their abdomen in a defensive display or deliver a mild sting. Escape prevention is important but not as critical as for tiny species, standard barriers and tight-fitting lids are sufficient.
