紹介

Polyrhachis feehani is a large ant species native to the Cooktown area in Queensland, Australia. Workers measure 10.78-11.79 mm in total length . Their body is black with reddish-brown appendages and a reddish-golden median patch on the gaster . This species belongs to the ammon species-group in the subgenus Hagiomyrma and is rare, with distribution limited to the Cooktown region . This ground-nesting species is rarely studied and not commonly kept in captivity. Much of its biology remains undocumented, but its large size makes it easier to observe .

Quick Summary

  • Difficulty: Hard
  • Origin & Habitat: Cooktown area, Queensland, Australia, ground-nesting in tropical coastal region [1]
  • Colony Type: Unknown, colony structure has not been documented. Sexuals (queens and males) are unknown in scientific collections [2]
  • Size & Growth:
    • Queen: Unknown, queen caste has not been described [2]
    • Worker: 10.78-11.79 mm total length [1]
    • Colony: Unknown, colony size has not been documented [2]
    • Growth: Unknown [2]
    • Development: Unknown, development timeline has not been studied [2] (No data available on egg-to-worker development time.)
  • Antkeeping:
    • Temperature: Aim for warm conditions around 24-28°C, based on tropical Queensland origin [1]
    • Humidity: Provide moderate to high humidity with a moist nest substrate, based on coastal climate [1]
    • Diapause: Unknown, no data on overwintering requirements [2]
    • Nesting: Ground-nesting species. Provide a soil-based setup or Y-tong/plaster nest with moist substrate [1]
  • Behavior: Behavior is poorly documented due to rarity. As a Formicinae species, Polyrhachis feehani lacks a functional sting and sprays formic acid for defense. They are likely docile, and their large size reduces escape risk, but standard barriers should still be used. They are ground-nesters that forage on the surface.
  • Common Issues: species rarity makes it difficult to obtain colonies for captive keeping., no established care protocols exist since few keepers have worked with this species., colony structure is unknown, making it unclear whether single-queen or multi-queen setups are appropriate., development timeline is unconfirmed, so keepers cannot predict growth rates., sexuals are unknown, meaning nuptial flight timing and queen reproduction details are undocumented.

Appearance and Identification

Polyrhachis feehani workers measure 10.78-11.79 mm in total length. They have a black body with reddish-brown appendages and a distinct reddish-golden median patch on the gaster. The mandibles are black with a reddish-brown band, and the body has various hairs, including long erect hairs on the mesosoma and petiole [1].

Distribution and Habitat

This species is known only from the Cooktown area in Queensland, Australia, and is documented as a ground-nesting species. It has been collected few times, making it rare [1][2].

Current State of Knowledge

Polyrhachis feehani was described in 2013 and remains poorly understood. Sexual castes are unknown, and immature stages are present in collections but not studied in detail [1][2].

Related Species and Comparison

Polyrhachis feehani belongs to the ammon species-group and is similar to species like P. darlingtoni, but can be distinguished by petiole shape [1].

Potential Care Approach

Based on its tropical origin, aim for warm temperatures around 24-28°C and moderate humidity. As a ground-nester, provide a soil-based nest with moist substrate. Diet likely includes sugar sources and protein, but no specific data exists [1].
