Camponotus johnclarki

Camponotus johnclarki

Camponotus johnclarki is a distinctive Australian carpenter ant that was originally placed in the genus Notostigma before being reclassified by Taylor in 1992. Workers are rarely encountered in the wild, but they have been observed foraging on Banksia tree trunks in woodland areas north of Perth, Western Australia. The species is recognized by its unusual morphology, including J-shaped setae on the mentum and an elongate propodeal spiracle. Minor workers have a particularly odd appearance with a posteriorly attenuated head capsule. This species is thought to belong to the C. wiederkehri group and represents a rare and somewhat mysterious member of the Australian ant fauna.

Quick Summary

• Difficulty: Unknown, limited data available
• Origin & Habitat: Western Australia, Australia. Found in woodland areas, particularly observed foraging on Banksia trunks north of Perth ^[1][2].
• Colony Type: Unconfirmed, likely single-queen colonies based on typical Camponotus patterns, but colony structure has not been documented.
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 10-14mm based on Camponotus genus patterns
  • Worker: Estimated 6-10mm based on Camponotus genus patterns
  • Colony: Estimated moderate to large (several hundred workers) based on genus patterns
  • Growth: Moderate, based on typical Camponotus development
  • Development: Estimated 6-10 weeks based on typical Camponotus development at warm temperatures (Development time is unconfirmed for this species. Estimates based on related Australian Camponotus species.)
• Antkeeping:
  • Temperature: Keep around 22-26°C. Australian species from temperate climate likely tolerates moderate warmth.
  • Humidity: Moderate humidity preferred. Western Australian woodland habitat suggests drier conditions than tropical species.
  • Diapause: Likely requires winter rest period (diapause) given temperate Western Australian origin. Provide 2-3 months at 10-15°C during winter.
  • Nesting: Likely nests in rotting wood or under bark in the wild. Captive colonies do well in Y-tong nests, acrylic nests, or wood-based formicaria.
• Behavior: Workers are rarely seen foraging, which suggests a somewhat secretive colony structure. Based on typical Camponotus behavior, they are likely moderate foragers that accept sugar water and protein sources. Escape risk is moderate, use standard Camponotus escape prevention.
• Common Issues: limited availability in the antkeeping hobby due to rare field encounters, colony founding may be slow due to limited documented breeding data, winter diapause requirements are not fully understood for this species, escape prevention should be maintained despite limited worker activity

Nest Preferences

In the wild, Camponotus johnclarki appears to nest in woodland habitats, with workers rarely encountered but observed foraging on Banksia trunks. This suggests they may nest in rotting wood or under bark in tree hollows. For captive colonies, Y-tong (AAC) nests work well for Camponotus species, as do acrylic nests with appropriate chambers. Wood-based formicaria also mimic their natural nesting preferences. Provide a nest with chambers sized appropriately for their moderate colony size. ^[1][2]

Feeding and Diet

Like other Camponotus species, C. johnclarki likely accepts a varied diet including sugar sources (honey water, sugar water) and protein (insects, mealworms, crickets). Carpenter ants are typically omnivorous and not specialized feeders. Offer sugar water constantly and protein prey 2-3 times per week. Remove uneaten prey after 24-48 hours to prevent mold. While specific prey preferences are unconfirmed for this species, they likely follow typical Camponotus foraging patterns.

Temperature and Seasonal Care

Maintain nest temperatures around 22-26°C for optimal brood development. As a Western Australian species from a temperate climate, they likely benefit from a temperature gradient allowing workers to choose their preferred warmth. During winter, provide a diapause period of 2-3 months at 10-15°C to simulate seasonal conditions. This winter rest is important for colony health and likely triggers reproductive cycles. Reduce feeding during diapause and avoid disturbing the colony.

Behavior and Colony Dynamics

This species is known for being rarely encountered in the wild, which suggests either low colony density or secretive foraging behavior. Workers have been observed foraging on Banksia trunks, indicating they may be more arboreal than some other Camponotus species. The minor workers have distinctive morphology with a posteriorly attenuated head capsule. Colonies likely grow at a moderate pace typical of carpenter ants, with nanitic (first) workers being smaller than subsequent generations. ^[1]
