Camponotus hartogi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Southern Australia (SA, Vic, WA) in sclerophyll forest communities. Nests arboreally in dead branches and rotting stumps ^[3][1].
• Colony Type: Unconfirmed, but likely single-queen based on typical Camponotus patterns.
• Size & Growth:
  • Queen: Size data unavailable.
  • Worker: Approximately 9mm ^[2]
  • Colony: Up to several hundred workers (estimated from genus patterns)
  • Growth: Moderate
  • Development: Estimated 6-10 weeks based on typical Camponotus development (Actual timing may vary with temperature and in the absence of species‑specific data.)
• Antkeeping:
  • Temperature: Keep at room temperature, roughly 20-26°C. A gentle gradient to allow self‑regulation is ideal.
  • Humidity: Keep the nest chamber dry, using a moisture gradient (e.g., a damp cotton plug or water tube in one corner). High humidity is not required and may even be harmful for this arboreal species.
  • Diapause: Likely required, given the southern Australian distribution. Reduce temperature to 10-15°C for 2-3 months during winter. Specific requirements are unconfirmed.
  • Nesting: Arboreal specialists, prefer wood‑ or cork‑based nests. Y‑tong (AAC) with wooden inserts or cork branches work well. Avoid plaster or soil setups.
• Behavior: Calm and non‑aggressive. As Subordinate Camponotini, they are not territorial. Workers are moderately active, comfortable climbing vertical surfaces. Escape risk is moderate, they are not tiny but can still squeeze through small gaps.
• Common Issues: standard test tube setups may cause stress, transition to a wood‑based nest as soon as the first workers emerge., winter diapause is likely needed but the exact duration and temperature are unconfirmed, monitor colony activity and adjust., specific humidity preferences are undocumented, start with a dry nest and watch for signs of desiccation or mold.

Housing and Nest Preferences

Camponotus hartogi is an arboreal nester that naturally lives in dead branches and rotting stumps ^[3]. In captivity, choose a nest that provides dry, wood‑based chambers, such as Y‑tong (AAC) with cork bark or hollow wood inserts. Avoid plaster or soil nests. The outworld should include vertical elements (cork branches, twigs) to encourage natural climbing. A water tube or damp cotton at one end of the nest gives access to moisture without making the whole chamber wet.

Feeding and Diet

Like most Camponotus, C. hartogi is omnivorous. Offer a varied diet: protein sources like small insects (fruit flies, tiny crickets, mealworms) 2-3 times per week, and a constant sugar source (honey water or sugar water). They may prefer food placed at elevated spots in the outworld. Remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Seasonal Care

Keep the nest at 20-26°C, with a gentle temperature gradient. Because they originate from southern Australia, a winter rest period is likely beneficial. Lower the temperature to 10-15°C for 2-3 months during winter. Reduce feeding during diapause. Since species‑specific data are lacking, watch for reduced activity as a sign to start the cool period. ^[1]

Colony Establishment

A newly mated queen can be started in a standard test tube setup, but once the first workers (nanitics) appear, transfer the colony to a wood‑based nest. The founding behaviour is unconfirmed for this species, but typical Camponotus patterns suggest a claustral start (queen seals herself in and raises the first brood without foraging). Development from egg to worker takes about 6-10 weeks at optimal temperatures. Growth is moderate, colonies take several years to reach full size.

Behavior and Temperament

C. hartogi is a Subordinate Camponotini, so it is peaceful and rarely aggressive toward other ants or the keeper ^[4]. Workers are moderate foragers and comfortable climbing. Their defense relies on biting and spraying formic acid (typical of Formicinae). Escape risk is moderate, standard escape‑proofing (fluon, mineral oil) is sufficient.
