Myrmica liui

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Inner Mongolia, China, alpine meadow at 2573m elevation ^[1]. This is a Palaearctic species adapted to cool, elevated grassland environments.
• Colony Type: Based on Myrmica genus patterns, likely monogyne (single queen colony) ^[2]. Colony structure is unconfirmed for this specific species.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Myrmica genus patterns as approximately 6-8 mm total length ^[2]
  • Worker: Size data unavailable, inferred from Myrmica genus patterns as approximately 4-5 mm total length ^[2]
  • Colony: Unknown, likely up to several hundred workers based on related Myrmica species ^[2]
  • Growth: Moderate, typical for Myrmica genus ^[2]
  • Development: Estimated 6-10 weeks at optimal temperature, inferred from Myrmica genus patterns ^[2] (Development time is temperature-dependent, cooler high-altitude origin may slow development compared to lowland species)
• Antkeeping:
  • Temperature: Keep at cool temperatures, roughly 18-22°C, based on alpine habitat ^[1]. Provide a temperature gradient for workers to choose preferred zones.
  • Humidity: Keep nest substrate consistently moist but not waterlogged, as this species nests in soil ^[1]. Allow slight drying between waterings.
  • Diapause: Yes, Myrmica species typically require winter hibernation ^[2]. Provide 2-3 months at 5-10°C during winter.
  • Nesting: Prefer soil-based nests. Use naturalistic setups with soil or plaster nests that mimic their alpine meadow habitat ^[1].
• Behavior: Myrmica liui workers are moderately aggressive and will sting when threatened, typical for Myrmica genus ^[2]. They are active foragers on the ground surface. Escape risk is moderate due to small size, use standard barriers to prevent escapes.
• Common Issues: high-altitude origin means they may struggle in warm conditions, keep them cool, hibernation is essential for colony health, skipping winter rest can lead to decline, founding colonies are fragile due to small initial size and sensitivity to disturbance, as a newly described species, captive husbandry is not well-established, be prepared to experiment, soil nesting preferences mean they may not thrive in nests without appropriate substrate

Nest Preferences

Myrmica liui naturally nests in soil within alpine meadows at high elevation ^[1]. In captivity, provide a naturalistic setup with soil or a dig-out formicarium. The species prefers compact chambers for tunneling. Use test tube setups for founding colonies, and move to plaster or Y-tong nests with damp soil substrate for established colonies. Keep the nest substrate moist but not waterlogged to mimic natural conditions.

Feeding and Diet

Myrmica liui is predatory and accepts small live prey such as fruit flies, pinhead crickets, and mealworms. Offer protein foods 2-3 times per week. Provide a constant sugar source like sugar water or honey. Remove uneaten prey within 24 hours to prevent mold. Based on Myrmica genus patterns, they may also collect honeydew from aphids ^[2].

Temperature and Seasonal Care

This species requires cooler temperatures due to its alpine origin. Keep the nest area at 18-22°C, with room temperature acceptable in most homes ^[1]. Avoid temperatures above 25°C. During winter, provide a hibernation period of 2-3 months at 5-10°C, as typical for Myrmica species ^[2]. Skipping hibernation can weaken colonies.

Behavior and Temperament

Workers are active foragers with typical Myrmica defensive behavior, they will sting if threatened ^[2]. Colonies are moderately aggressive and defend against intruders. Escape prevention is important due to small worker size, use fluon barriers and check for gaps. Workers are ground-dwelling and do not climb well, reducing vertical escape risk.
