Myrmica hamulata

Myrmica hamulata

Myrmica hamulata is a small reddish-brown ant native to the southwestern United States. Workers measure around 4-6mm and have the characteristic Myrmica features including a well-developed stinger and relatively long legs. The species was originally described as a subspecies of Myrmica sabuleti before being elevated to full species status. These ants are found in higher elevation habitats in New Mexico, typically around 8,000 feet in mountainous areas. As a Myrmica species, they likely share the genus typical behavior of forming single-queen colonies and preferring cooler, more temperate conditions compared to many ant species.

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to the southwestern United States, specifically New Mexico (Hayne's Canyon, Sacramento Mountains at 8,000 ft elevation). Found in mountainous, cooler habitats in the Nearctic region ^[1][2][3].
• Colony Type: Single-queen colonies (monogyne) based on typical Myrmica patterns. Colony structure for this specific species has not been directly studied.
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 6-8mm based on typical Myrmica queen size ^[3]
  • Worker: Estimated 4-6mm based on typical Myrmica worker size ^[3]
  • Colony: Unknown for this specific species, typical Myrmica colonies reach several hundred to a few thousand workers
  • Growth: Moderate, based on typical Myrmica development patterns
  • Development: 6-10 weeks at optimal temperature based on genus-level data for Myrmica species (Development time inferred from related Myrmica species. Cooler mountain habitat may result in slower development.)
• Antkeeping:
  • Temperature: Keep at 18-22°C, these are mountain ants adapted to cooler conditions. Avoid overheating. Room temperature or slight cooling is appropriate ^[3].
  • Humidity: Moderate humidity around 50-60%. Keep nest substrate slightly moist but allow some drying areas. These ants are from an elevated, drier mountain habitat ^[3].
  • Diapause: Yes, Myrmica species require hibernation. Provide a cold period around 5-10°C for 3-4 months during winter ^[3].
  • Nesting: In captivity, standard test tubes or Y-tong nests work well. They likely prefer soil-based nests with some dry chambers. Avoid overly humid conditions.
• Behavior: Typical Myrmica temperament, not particularly aggressive but will sting if threatened. Workers are active foragers, likely collecting honeydew and small prey. Escape risk is moderate, standard barrier methods (Fluon) are sufficient. They are diurnal and actively forage during cooler parts of the day.
• Common Issues: overheating is a major risk, these mountain ants do poorly in warm conditions, hibernation failure can cause colony decline, must provide proper cold period, wild-caught colonies may have parasites that kill them in captivity, poor escape prevention leads to losses, they are active and will explore for exits

Housing and Nest Setup

Myrmica hamulata can be kept in standard test tube setups for founding colonies. Once the colony reaches 20-30 workers, you can move them to a Y-tong nest or a naturalistic setup. Since they come from mountainous New Mexico habitats, they prefer cooler temperatures and moderate humidity. Use a substrate that holds some moisture but also allows for drier areas, a mix of soil and sand works well. Avoid overheating the nest area, as this species is adapted to cooler conditions at higher elevations. ^[1][3]

Feeding and Diet

Like other Myrmica species, these ants are omnivorous. They collect honeydew from aphids and tend scale insects in the wild, so sugar water or honey water should be available at all times. For protein, offer small insects like fruit flies, small crickets, or mealworms. They are active hunters and will take live prey. Feed protein sources 2-3 times per week, and keep sugar water constantly available. Remove uneaten prey after 24-48 hours to prevent mold issues. ^[3]

Temperature and Seasonal Care

This is a critical aspect of keeping Myrmica hamulata. They are mountain ants from around 8,000 feet elevation in New Mexico, so they prefer cooler temperatures than most ant species. Keep the nest area between 18-22°C, room temperature is often ideal. Never use heating cables or heat mats with this species as they can easily overheat. During winter, you must provide a hibernation period of 3-4 months at 5-10°C (like in a refrigerator or cold garage). Failure to provide proper hibernation will weaken and eventually kill the colony. ^[1][2][3]

Colony Development

Myrmica hamulata colonies grow at a moderate pace. After the queen lays her first eggs, expect 6-10 weeks until the first workers (nanitics) emerge, based on typical Myrmica development timelines. The founding stage is claustral, the queen seals herself in a chamber and raises the first brood alone using her stored fat reserves. Do not disturb the queen during this time. Once the first workers emerge, they will take over foraging and brood care. Colonies of this species can eventually reach several hundred to a few thousand workers. ^[3]

Behavior and Defense

Workers of Myrmica hamulata are not particularly aggressive but possess a functional stinger and will use it if they feel threatened. They are diurnal foragers, most active during cooler parts of the day, this matches their mountain habitat where temperatures remain moderate. Workers are medium-sized and relatively fast-moving. They use chemical trails to recruit nestmates to food sources. Escape prevention is important but not as critical as with tiny ants, standard barrier methods like Fluon on test tube rims work well. They are not known for being particularly escape-prone. ^[3]
