Strumigenys behasyla

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Democratic Republic of Congo, IT Province ^[1]. Strumigenys species typically inhabit humid forest floors, nesting in rotting wood, leaf litter, or under stones in shaded, damp areas.
• Colony Type: Probably single-queen colonies based on typical Strumigenys patterns, though the social structure has not been confirmed for this species.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Strumigenys genus (approx. 4-6 mm).
  • Worker: Size data unavailable, inferred from Strumigenys genus (approx. 3-4 mm).
  • Colony: Up to about 200 workers at maturity, based on typical genus patterns.
  • Growth: Slow
  • Development: Estimated 8-12 weeks, based on related species. (Development times are longer than many common ant species. First workers (nanitics) are much smaller than mature workers.)
• Antkeeping:
  • Temperature: Keep at 22-26°C. As a tropical species, they need warm, stable conditions. Avoid temperatures below 20°C.
  • Humidity: High humidity is essential. Keep the nest substrate consistently moist but not waterlogged. Provide ventilation to prevent mold, but avoid dry conditions.
  • Diapause: No true diapause needed. Being from tropical central Africa, they don't need cold hibernation. Slight winter cooling may slow activity but isn't required.
  • Nesting: Y-tong (AAC) or plaster nests work well for holding moisture. Avoid overly dry setups. Provide tight, enclosed chambers suitable for small colonies.
• Behavior: These ants are slow-moving ambush hunters. Workers patrol slowly, often pausing, and snap their mandibles on small prey within range. They are not aggressive toward humans and rarely sting, though they have a functional stinger (subfamily Myrmicinae). Because they are tiny, escape prevention is critical, use fine mesh or barriers on any gaps.
• Common Issues: high humidity needs can lead to mold if ventilation is too poor, slow growth may test a beginner's patience, tiny size makes escape prevention essential, check all seals regularly, specialized diet of live springtails or similar prey may be hard to maintain, colonies stay small even when mature, which is normal for this genus

Housing and Nest Setup

Strumigenys behasyla needs a setup that holds high humidity while allowing some airflow. Y-tong (AAC) or plaster nests are good because they absorb and release moisture slowly. Use small chambers, they don’t need large open spaces. A small outworld for feeding is fine. Use fluon or other barriers on tube connections to prevent escapes. Test tubes can work for founding colonies, but they dry out quickly, so check humidity often.

Feeding and Diet

You must provide live prey for this specialized predator. Springtails are the best choice, as their trap‑jaw mandibles are suited for catching small fast prey. Fruit flies, tiny crickets, or small mealworms may also work. Offer fresh prey every few days and remove leftovers after a day. Sugar water or typical ant feeds are not necessary because Strumigenys are not honeydew feeders.

Temperature and Seasonal Care

Keep the nest at 22-26°C year round. These tropical ants don’t need hibernation. You can use a small heating cable on one side to create a warm spot, but give them a cooler area to choose from. A slight drop to around 20°C in winter is okay, but avoid going colder.

Behavior and Observation

Watch for their unique hunting method: workers patrol slowly, stop often, and then snap their mandibles shut on any prey that comes close. They ambush rather than chase. They are calm with nestmates and not aggressive toward you. Their stinger is small and they rarely use it on humans.
