Camponotus guidae

Quick Summary

• Difficulty: Medium
• Origin & Habitat: South Australia, found in temperate woodland and scrubland across multiple locations including McLaren Flat, Hatherleigh Hills, Innes National Park, Monarto, Piccaninny Road, Rockleigh, Western River, Woakwine Cutting, and Woakwine Range ^[1][2]. The species is ground-nesting ^[2].
• Colony Type: Presumed monogyne based on typical Camponotus patterns. Colonies are dimorphic with major and minor workers but no medium workers observed ^[1][2].
• Size & Growth:
  • Queen: Size data unavailable for this species, inferred from Camponotus genus patterns to be approximately 12-15mm
  • Worker: Size data unavailable, minor workers cannot be accurately measured from the provided morphometric data. The research provides head measurement equations but not total body length.
  • Colony: Maximum colony size unknown, estimated several hundred workers based on typical Camponotus development
  • Growth: Moderate, based on typical Camponotus development patterns
  • Development: Development time unconfirmed for this species, estimates based on related Camponotus species suggest several months (Direct development data unavailable for this species)
• Antkeeping:
  • Temperature: Keep at room temperature (18-24°C) with a warm area (around 25°C) available. Provide a temperature gradient so ants can choose their preferred zone. Inferred from South Australian temperate climate.
  • Humidity: Moderate humidity, ground-nesting species from temperate South Australia prefer well-drained but not dry conditions. Keep nest substrate slightly moist but allow drying between waterings.
  • Diapause: Yes, South Australian temperate climate requires winter hibernation. Reduce temperature to 10-15°C for 2-3 months during winter (May-August in Southern Hemisphere). Inferred from geographic range.
  • Nesting: Ground-nesting species, will do well in Y-tong nests, plaster nests, or naturalistic setups with soil. Provide deep enough chambers for the queen and colony. Avoid overly humid conditions that can cause mold ^[2].
• Behavior: Generally calm and non-aggressive for a Camponotus species. Workers are moderate foragers, typically searching for honeydew and small insects. Major workers can deliver a pinch with their mandibles but are not particularly aggressive. Escape prevention should be moderate, standard barriers work well. Primarily nocturnal or crepuscular in foraging patterns, typical of Australian carpenter ants.
• Common Issues: lack of biological data means care is based on genus-level inference, monitor colony behavior and adjust conditions accordingly, winter hibernation is essential for this temperate species, skipping it can weaken or kill the colony, ground-nesting species needs proper substrate depth and moisture balance, too wet causes mold, too dry stresses the colony, slow founding phase is normal, Camponotus queens can take months to produce first workers, don't give up too soon, major workers may appear intimidating but are not aggressive, handle gently during nest transfers

Nest Preferences

Camponotus guidae is a ground-nesting species, which means they naturally excavate nests in soil or use existing cavities in the ground. In captivity, they adapt well to various nest types. Y-tong (AAC) nests work well, choose one with chambers at least 10-15mm deep to accommodate the queen and future brood. Plaster nests are another good option as they allow you to control humidity more precisely. For a naturalistic setup, use a deep container (at least 5cm) filled with a soil-sand mix that holds its shape when tunnels are dug. The nest should be kept in a dark or dimly lit area, as carpenter ants prefer sheltered, low-light conditions. Provide a water tube or moisture source connected to the nest area so workers can access water without flooding the brood chambers. ^[2]

Feeding and Diet

Like other Camponotus species, these ants are omnivorous with a preference for sugar sources and protein. Provide a constant supply of sugar water (1:3 ratio sugar to water) or honey (diluted slightly for easier access). For protein, offer small insects like fruit flies, small crickets, or mealworms, adjust size to match your worker ants. Minor workers can handle small prey, while major workers can tackle larger items. Feed protein 2-3 times per week, removing any uneaten prey after 24 hours to prevent mold. Some keepers report that Australian Camponotus species accept cat food or other prepared protein sources. Always ensure fresh water is available. During hibernation, reduce feeding significantly as metabolic activity slows.

Temperature and Seasonal Care

This species comes from temperate South Australia, so it needs distinct seasonal variation. Keep the nest at room temperature (18-24°C) year-round, with a warmer area around 25°C available on one side. During the active season (spring through autumn), this temperature range supports normal colony function and brood development. Come winter (May through August in the Southern Hemisphere), you must simulate hibernation by reducing temperatures to 10-15°C. This can be done by moving the colony to a cooler room, garage, or refrigerator (not freezer). Do not feed during hibernation, but keep a small water source available. Hibernation is critical for this temperate species, skipping it can weaken the colony and shorten the queen's lifespan. Resume normal feeding and temperatures gradually in spring.

Behavior and Colony Dynamics

Camponotus guidae forms dimorphic colonies with distinct major and minor worker castes. Minor workers handle most foraging, brood care, and nest maintenance, while major workers (soldiers) defend the colony and help process larger food items. The colony grows relatively slowly at first, the claustral queen seals herself in and raises the first brood (nanitic workers) entirely alone. This founding phase can take several months, so patience is essential. Once the first workers emerge, the colony typically grows steadily. Major workers appear as the colony matures, usually when the worker population reaches several dozen. These ants are generally calm and less aggressive than some other carpenter ant species, but they will defend if threatened. Workers are primarily nocturnal, so you may see more activity in the evening hours.
