Strumigenys dohertyi

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Southeast Asia and southern China – found in leaf litter and rotting wood in tropical and subtropical forests ^[2][1]. Collected from secondary forests and disturbed forest areas at elevations up to 1400m in Sumatra ^[2].
• Colony Type: Unknown from available research. Most Strumigenys are monogyne, but this is not confirmed for Strumigenys dohertyi.
• Size & Growth:
  • Queen: Not recorded in available literature.
  • Worker: 2.0–3.0mm total length ^[1]
  • Colony: Unknown from available research.
  • Growth: Unknown
  • Development: Unknown – not studied in captivity (No published data on development time.)
• Antkeeping:
  • Temperature: Based on tropical origin from lowland forests, maintain warm temperatures around 24–28°C. Avoid drops below 20°C.
  • Humidity: High humidity is essential – they naturally live in leaf litter and rotting wood. Keep the nest substrate consistently moist but not waterlogged. Target 70–85% humidity in the nest area.
  • Diapause: No – this is a tropical species from Southeast Asia with no cold tolerance requirement. They remain active year-round.
  • Nesting: Prefers humid, dark environments. In captivity, a naturalistic setup with moist substrate or a Y‑tong/plaster nest works well. They do well in test tube setups with access to a humid outworld.
• Behavior: Tiny, slow-moving ants that are entirely predatory on micro‑arthropods like springtails and mites. They are not aggressive and pose no threat to humans. Workers forage individually in leaf litter. Escape prevention is critical due to their very small size – they can squeeze through standard mesh barriers.
• Common Issues: escape prevention is critical – they are tiny enough to squeeze through standard mesh barriers, colonies often fail from drying out – they require consistently high humidity, they require live micro‑prey – they will not accept sugar or dead food, overfeeding can lead to mold and pest problems

Housing and Nest Setup

Strumigenys dohertyi requires excellent escape prevention due to their tiny 2–3mm size. Use test tubes with tight‑fitting cotton plugs or Y‑tong nests with very fine mesh barriers. They need high humidity – a naturalistic setup with moist substrate works well, or keep test tubes in a humidified outworld. A small formicarium with narrow chambers scaled to their tiny size is ideal. Provide a water tube and keep the nest area humid. They do not need light and prefer dark, enclosed spaces similar to their natural leaf litter habitat ^[2][1].

Feeding and Diet

This species is an obligate predator on micro‑arthropods. In captivity, their primary food should be live springtails – this is essential and they will not thrive on dead food or sugar sources. They may accept other tiny live prey like micro‑arthropods, but springtails should form the bulk of their diet. Feed every 2–3 days, offering enough prey for the colony to consume within 24 hours. Remove uneaten prey to prevent mold. Do not offer honey, sugar water, or other carbohydrates.

Temperature and Seasonal Care

Keep Strumigenys dohertyi at 24–28°C – they are tropical ants from warm Southeast Asian forests ^[2]. Room temperature (20–24°C) may be slightly cool, consider using a gentle heat source like a heating cable on one side of the nest to create a warm zone. They do not require hibernation or diapause. Avoid temperature drops below 20°C and sudden temperature changes. Maintain stable, warm conditions year‑round.

Colony Establishment

Little is known about colony founding in this species. If you obtain a queen, keep her in a small test tube setup with moist cotton, high humidity, and no light exposure. She may seal herself in. Once workers appear, slowly introduce tiny live springtails. Colony growth rate is unknown – be patient and do not overfeed.

Behavior and Temperament

Strumigenys dohertyi workers are slow‑moving and non‑aggressive. They forage individually through leaf litter and soil, hunting micro‑arthropods rather than scavenging. They have very small eyes (only 3–5 ommatidia) and navigate primarily using chemical trails and tactile cues ^[1]. When disturbed, they may freeze or flee rather than attack. They pose no stinging risk to humans.
