Notoncus hickmani

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Southwestern Australia, particularly the Perth region. Thrives in Mediterranean climate with warm, dry summers and mild, wet winters ^[1].
• Colony Type: Unconfirmed, colony social structure has not been documented.
• Size & Growth:
  • Queen: Size data unavailable.
  • Worker: Size data unavailable.
  • Colony: Unknown, no documented estimate.
  • Growth: Unknown, no data.
  • Development: Unknown, no specific data available. (No development timeline has been documented for this species.)
• Antkeeping:
  • Temperature: No specific temperature data from research. Based on its Mediterranean habitat, provide a gradient around 22‑26°C and observe colony behavior.
  • Humidity: No specific data. Given the dry southwestern Australian climate, keep the nest moderately dry with a small moist area, avoid waterlogging.
  • Diapause: Likely necessary as a temperate species, but exact conditions are unknown. Many Australian temperate ants require a winter diapause. Provide a cooler period (10‑15°C) for 2‑3 months if colony activity slows in winter.
  • Nesting: In nature, probably nests in soil or under stones. In captivity, use a Y‑tong or plaster nest with small chambers and a humidity gradient.
• Behavior: Active foragers, likely generalist omnivores (typical of Melophorini). Not aggressive. Small size means you must take escape prevention seriously, use tight seals and barriers like fluon or oil.
• Common Issues: limited availability in the hobby, this species is rarely traded, colony founding and social structure are completely unconfirmed, you may need to experiment with care, specific temperature, humidity, and diapause requirements are unknown, so be prepared to adapt based on observations, escape risk due to small size, ensure nest and outworld are sealed properly

Natural History and Distribution

Notoncus hickmani is endemic to southwestern Australia, with its range centered on the Perth region in Western Australia. It is considered common in its natural habitat. The species has been recorded from all Australian mainland states except the Northern Territory ^[1]. Originally described by Clark in 1930,it was later placed in Prolasius and then returned to Notoncus by Brown in 1955,who also synonymized Notoncus hickmani with this species ^[2]. The genus Notoncus belongs to the tribe Melophorini, which contains various Australian ants.

Identification and Morphology

Key identification features for Notoncus hickmani include: scutellum absent or at best weakly differentiated, no prominent processes on the trunk, the metanotal spiracles may be connected by a low ridge, humeri (shoulders) rounded, not projecting, antennal scapes rarely longer than the head including clypeus, and usually shorter. These features help distinguish this species from other Notoncus ^[2].

Housing and Nesting

No specific nesting data exists for this species. Following general practices for small Australian Formicinae, use a Y‑tong or plaster nest with small, compact chambers. Keep the nest at a temperature gradient around 22‑26°C, a heating cable on one side works well. Humidity should be low to moderate: allow the nest to dry slightly between waterings, but provide a small moist area. For founding, a standard test tube setup is a good starting point. Because workers are small, ensure the outworld has tight seals and apply fluon or oil barriers to prevent escapes.

Feeding and Diet

Notoncus hickmani is assumed to be a generalist omnivore, like other Melophorini. Offer sugar water or honey water constantly as a carbohydrate source. Provide protein 2‑3 times per week in the form of small insects such as fruit flies, small mealworms, or pinhead crickets. Remove uneaten protein after 24‑48 hours to prevent mold. Always keep fresh water available.

Seasonal Care and Diapause

As a species from temperate Western Australia, Notoncus hickmani likely experiences winter cooling. If your colony is from that region, consider providing a diapause period of 2‑3 months at 10‑15°C. However, exact requirements are unconfirmed. Observe colony activity: if workers slow down in winter, reduce temperature gradually and allow a cool rest. Do not force diapause if the colony is active and growing.
