Camponotus darlingtoni

Quick Summary

• Difficulty: Medium
• Origin & Habitat: South-western Australia, specifically the Perth region and Rottnest Island in Western Australia, with additional populations in South Australia. They inhabit woodland areas and are ground-nesting, found under stones and logs ^[1][2].
• Colony Type: Colony type is unconfirmed. Specific literature on queen number for this species is not available.
• Size & Growth:
  • Queen: 11mm (dealated queen) ^[3]
  • Worker: Minima 4-5.5mm, media 7-7.5mm, maxima 8-9mm ^[3]
  • Colony: Colony size data unavailable, no specific studies document maximum colony size for this species
  • Growth: Growth rate is unconfirmed, specific development studies are not available for this species
  • Development: Development time is unconfirmed for this species (Specific development studies are not available. Camponotus genus typically takes several months from egg to worker.)
• Antkeeping:
  • Temperature: Keep at 22-26°C. As a species from southwestern Australia, they prefer warm conditions but not extreme heat. A temperature gradient allowing workers to choose their preferred zone is ideal.
  • Humidity: Moderate humidity around 50-60%. Being ground-nesting ants from southwestern Australia (Mediterranean climate), they tolerate drier conditions than tropical species but need some moisture. Provide a water tube for drinking access.
  • Diapause: Diapause requirements are unconfirmed for this specific species. Based on geographic range (temperate southwestern Australia), a winter rest period may be beneficial.
  • Nesting: Ground-nesting species that does well in Y-tong (AAC) nests, plaster nests, or naturalistic setups with soil. Provide a nest chamber with moderate humidity and some dry areas for workers to regulate moisture. Test tube setups work for founding colonies ^[2].
• Behavior: Typical Camponotus temperament, generally non-aggressive and docile. Workers are moderate foragers and will scavenge for protein and sugar sources. Major workers have larger heads for cutting and processing food. Escape risk is moderate due to their size, standard barrier methods work well.
• Common Issues: colonies may decline if kept too cold, maintain warm temperatures, overfeeding can lead to mold in nest setups, remove uneaten protein promptly, ground-nesting species needs proper substrate moisture, too dry causes desiccation, too wet causes flooding, wild-caught colonies may carry parasites, quarantine and observe new colonies

Nest Preferences and Setup

Camponotus darlingtoni is a ground-nesting species that naturally nests under stones and logs in woodland areas ^[2]. In captivity, they do well in Y-tong (AAC) nests, plaster nests, or naturalistic setups with soil substrate. For founding colonies, a standard test tube setup works well, fill one test tube with water reservoir and provide a dark, quiet space for the queen. Once the colony reaches 15-20 workers, you can consider moving them to a formicarium. Provide a temperature gradient within the nest (22-26°C) so workers can regulate their conditions. The nest should have chambers sized appropriately for the colony size.

Feeding and Diet

Like most Camponotus species, C. darlingtoni is omnivorous. They accept sugar sources (honey water, sugar water, ripe fruit) and protein sources (insects like mealworms, crickets, fruit flies). In the wild, they forage for honeydew from aphids and scale insects, plus dead insects and nectar. Feed protein 2-3 times per week for growing colonies, and provide a constant sugar source. Remove uneaten protein within 24-48 hours to prevent mold. Minor workers handle food processing and distribution to the colony. Major workers can help cut up larger prey items.

Temperature and Seasonal Care

Maintain nest temperatures between 22-26°C for optimal brood development. As a species from southwestern Australia (Mediterranean climate), they experience cool, wet winters and warm, dry summers. During winter, you may reduce temperatures slightly to provide a rest period, but specific diapause requirements are unconfirmed for this species. Room temperature (18-22°C) is acceptable if your home stays in this range, but a slight heat source on one side of the nest creates a beneficial gradient.

Behavior and Colony Dynamics

Camponotus darlingtoni has typical carpenter ant behavior, docile, non-aggressive, and easy to handle. Workers are moderately active and will establish foraging trails once a colony is established. Major workers have larger heads and can assist with food processing. Workers may live several years, with the queen potentially living many years. New colonies are established through nuptial flights, winged queens and males mate, then queens shed wings and dig founding chambers.
