Aenictus kodaguensis

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Karnataka, India (Western Ghats), evergreen forests and grassland shola habitat at 1185-1476m elevation with 6000-7000mm annual rainfall ^[1]
• Colony Type: Unknown, only workers described ^[1]
• Size & Growth:
  • Queen: Unknown, queens undescribed ^[1]
  • Worker: 3.6-4.2 mm ^[1]
  • Colony: Unknown
  • Growth: Unknown
  • Development: Unknown (Development data unavailable, only workers are known for this species ^[1])
• Antkeeping:
  • Temperature: 10-34°C based on wild habitat range ^[1]
  • Humidity: Very high, rainforest habitat with 6000-7000mm annual rainfall ^[1]
  • Diapause: Unlikely required, tropical origin with year-round warm temperatures ^[1]
  • Nesting: Forms bivouacs under rotting logs in leaf litter ^[1]
• Behavior: Army ant behavior is expected but unconfirmed for this species. Workers are tiny and fast, creating high escape risk. As an Aenictus species, they likely function as nomadic predators of other insects ^[1].
• Common Issues: only workers are described, no queens available to establish captive colonies., army ants require specialized housing with large foraging areas., specific dietary needs are unknown but likely require live prey such as termites or other ants., maintaining rainforest humidity levels is extremely difficult in captivity., bivouac-forming species do not accept static nest structures like test tubes or formicaria.

Identification and Physical Appearance

Workers of Aenictus kodaguensis are small, measuring 3.6-4.2mm in total length ^[1]. They have a rectangular head that is longer than broad, with a distinctive black patch on the vertex ^[1]. The body is dark reddish brown to black, with a black abdomen that has a yellow apical tip ^[1]. A key identifying feature is the shagreened first gastral tergite, this means the surface has a rough, textured appearance similar to fine leather ^[1][2]. They also have a unique transverse ridge across the side of the mesosoma, dividing the mesopleuron from the metapleuron ^[1]. The antennae have 10 segments with relatively short scapes (scape index SI

Natural Habitat and Distribution

This species is only known from two locations in Karnataka, India: Pushpagiri Wildlife Sanctuary (type locality at 1476m elevation) and Honey Valley private estate (1185m elevation) ^[1]. Both sites are in the central Western Ghats ^[1]. The habitat consists of evergreen forests and grassland shola, a type of high-altitude stunted forest typical of the Western Ghats ^[1]. This region receives enormous amounts of rain, with annual precipitation between 6000-7000mm ^[1]. Temperatures range from 10-34°C throughout the year ^[1]. Specimens were collected in April before the monsoon season, either from under large rotting logs where bivouacs were present, or from leaf litter ^[1].

Why Captive Keeping Is Not Recommended

You cannot currently keep Aenictus kodaguensis in captivity because researchers have only described the worker caste ^[1]. Without queens, you cannot start a colony. Even if queens were eventually found, this species shows typical army ant biology that makes captive keeping extremely difficult. They form bivouacs, temporary nests made of living ants, rather than using permanent nest structures ^[1]. Army ants are nomadic and require vast foraging territories to hunt prey, often other ants or termites. Standard ant-keeping equipment like test tubes, Y-tong nests, or formicaria cannot accommodate their biological needs. Additionally, the specific dietary requirements for this species are unknown, though related army ants require large amounts of live prey.
