Myrmicaria adpressipilosa

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Native to Southeast Asia, found in Borneo, Java (Indonesia), Malaysia, and Singapore. Associated with primary or mature secondary forest, with records from Nee Soon forest and forest edges in Singapore ^[2], and lowland rainforest sites in Borneo ^[1].
• Colony Type: Colony structure is unconfirmed, no specific data on queen number or social organization.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Myrmicaria genus patterns
  • Worker: Size data unavailable, inferred from Myrmicaria genus patterns
  • Colony: Unknown, no specific data on colony size
  • Growth: Moderate, inferred from tropical ant patterns
  • Development: 6-10 weeks, estimated based on tropical ant development patterns (Development time is estimated, warmer temperatures may speed development)
• Antkeeping:
  • Temperature: Keep warm at 24-28°C, inferred as a tropical species from Southeast Asia
  • Humidity: Keep nest substrate consistently moist but not waterlogged, inferred from forest habitat ^[2]
  • Diapause: No, tropical species do not require hibernation
  • Nesting: Prefer soil or rotting wood in forest settings, in captivity, use Y-tong, plaster, or soil nests with humid conditions, inferred from habitat ^[2]
• Behavior: Defensive and will sting when threatened, primary defense is a sting with piperidine alkaloids, typical of Myrmicinae tribe Solenopsidini. Active foragers that hunt prey. As a tramp species, adaptable but escape prevention is important due to moderate size.
• Common Issues: stings during colony disturbances due to defensive behavior, escape risk due to moderate size, ensure tight seals on setups, maintaining warm and humid conditions year-round can be energy-intensive, invasive species warning, do not keep in non-native countries to prevent ecological damage

Housing and Nest Setup

Use a naturalistic setup that mimics forest floor habitat. A Y-tong (AAC) nest or plaster formicarium with soil chambers works well. These ants prefer enclosed, humid spaces with moderate chamber size. Provide a water reservoir to maintain humidity, but avoid direct water contact with the colony. An outworld area allows for foraging. For founding colonies, use a test tube setup, transitioning to a larger nest once the colony grows. Ensure the setup allows observation while maintaining dark, humid conditions ^[2][1].

Feeding and Diet

This species is primarily predatory, hunting small invertebrates in nature. In captivity, offer protein sources such as small crickets, mealworms, fruit flies, and other small insects. They may accept sugar water or honey as supplemental energy. Feed every 2-3 days, adjusting based on colony consumption. Remove uneaten prey after 24 hours to prevent mold. A varied diet supports colony health.

Temperature and Seasonal Care

Maintain temperatures between 24-28°C year-round for optimal activity. Use a heating cable on one side of the nest to create a gradient. Avoid temperatures below 20°C, as this can slow development. No hibernation is required, these ants remain active when kept warm.

Behavior and Temperament

Myrmicaria ants are defensive and will sting when threatened, using venom composed of piperidine alkaloids. They are active foragers that hunt prey. As a tramp species, they are adaptable, but escape prevention is important due to their moderate size. Monitor for aggression during colony maintenance.

Growth and Development

Colony growth is moderate, with founding queens raising the first brood alone. Development from egg to worker likely takes 6-10 weeks under warm conditions. Growth rate is steady with proper care. Exact colony size maximums are unknown.
