Myrmica mifui

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Mountain meadows at 3020m elevation in Shaanxi, China (Taibai Mountain) ^[1]. This is a Palaearctic region species from high-altitude alpine meadows.
• Colony Type: Colony structure is unconfirmed. Based on typical Myrmica patterns, likely single-queen (monogyne) colonies.
• Size & Growth:
  • Queen: Unknown, queens have not been described ^[1]. Inferred from Myrmica genus patterns, likely around 7-9mm.
  • Worker: Size data unavailable, the original description only provides head measurements (1.54-1.58mm HL), not total body length. Inferred from Myrmica genus, workers are approximately 4-6mm.
  • Colony: Unknown, no colony size data available. Inferred from related Myrmica species, colonies likely reach several hundred to a few thousand workers.
  • Growth: Unknown, likely moderate based on typical Myrmica development patterns.
  • Development: Unconfirmed. Based on typical Myrmica genus patterns, expect 6-10 weeks at optimal temperature. (Development time is estimated from related Myrmica species since no species-specific data exists.)
• Antkeeping:
  • Temperature: Keep at 18-22°C initially. As a high-altitude mountain species from 3020m, this ant likely prefers cooler conditions than typical Myrmica. Adjust based on colony activity, workers should be active but not clustering excessively on heat sources.
  • Humidity: Mountain meadow habitat suggests moderate humidity needs. Keep nest substrate lightly moist but not waterlogged, with some drier areas available for the ants to self-regulate.
  • Diapause: Yes, as a temperate high-altitude species from central China, this ant requires a winter dormancy period. Provide 3-4 months of cold conditions around 5-10°C during winter.
  • Nesting: Nesting site is unknown in the wild ^[2]. Based on typical Myrmica behavior and the mountain meadow habitat, they likely nest in soil or under stones. In captivity, a test tube setup or Y-tong nest with moist substrate works well. Provide a temperature gradient allowing them to choose their preferred zone.
• Behavior: Temperament is typical of Myrmica, workers are active foragers and will defend the nest if threatened. Like most Myrmica, they have a functional stinger capable of penetrating human skin, though the pain level is mild to moderate. Workers are moderately sized and good climbers, so escape prevention should include standard barriers. They likely forage for small insects and tend honeydew-producing aphids, similar to other Myrmica species.
• Common Issues: high-altitude origins mean this species may be sensitive to overheating, keep away from direct heat sources, limited data means colony development may be slower than expected since founding behavior is unconfirmed, winter dormancy is essential, failing to provide proper diapause will weaken or kill the colony, escape prevention is needed though workers are not particularly small, wild-caught colonies may carry parasites that affect survival in captivity

Housing and Nest Setup

Since the natural nesting site is unknown for this species, we rely on what works for related Myrmica species. A test tube setup works well for founding colonies, fill a test tube one-third with water, plug with cotton, and place the queen in a dark area. For established colonies, a Y-tong nest or a naturalistic setup with moist soil works well. Given their high-altitude origin, avoid overheating, room temperature is likely sufficient or even slightly cool. Provide a temperature gradient so the ants can choose their preferred zone. The nest substrate should remain lightly moist but never waterlogged. ^[1][2]

Feeding and Diet

Myrmica mifui will likely accept the standard Myrmica diet: small insects (fruit flies, pinhead crickets, mealworms) as protein sources and sugar water or honey as carbohydrates. In the wild, they probably forage for small invertebrates and collect honeydew from aphids. Feed protein prey 2-3 times per week and keep a constant sugar water source available. Remove uneaten prey after 24-48 hours to prevent mold. Since this is a newly described species with no documented feeding observations, start with proven Myrmica foods and adjust based on what your colony accepts. ^[2]

Temperature and Seasonal Care

This is a high-altitude species from 3020m elevation, suggesting adaptation to cooler conditions than typical lowland Myrmica. Keep the nest area in the 18-22°C range initially and observe colony behavior. If workers consistently cluster in cooler areas, reduce temperature. If they seem sluggish, slightly increase warmth. During winter, provide a proper diapause period of 3-4 months at 5-10°C, this is essential for the health of temperate species. A refrigerator cold-room or garage that stays cool over winter works well. Do not feed during diapause but keep the nest slightly moist. ^[1]

Colony Development

Since Myrmica mifui was only described in 2016,there is no published data on colony development or founding behavior. Based on typical Myrmica genus patterns, the queen likely seals herself in a claustral chamber and raises the first brood alone on stored fat reserves. First workers (nanitics) should emerge after several months, though exact timing is unknown. Growth rate is likely moderate, faster than some slow-growing genera but not as rapid as tropical species. Be patient with founding colonies, as they can take many months to establish. The colony will remain small for the first year but should grow steadily once workers emerge. ^[1]
