Strumigenys chareta

Quick Summary

• Difficulty: Unknown
• Origin & Habitat: New Caledonia, specific habitat preferences unknown ^[1].
• Colony Type: Unknown, no published data on social structure.
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: size data unavailable
  • Growth: Unknown
  • Development: Unknown (No specific data available for this species.)
• Antkeeping:
  • Temperature: Unknown, as a tropical species, likely needs warm conditions (around 24-28°C) but no precise data confirmed.
  • Humidity: Unknown, likely high humidity based on tropical forest floor habitat, but not confirmed.
  • Diapause: Not required, inferred from tropical origin.
  • Nesting: Unknown, no published data on nesting preferences. Based on genus, they may prefer moist, naturalistic substrates.
• Behavior: No species-specific data. Based on the genus Strumigenys and the subfamily Myrmicinae/tribe Attini defense mechanism, these ants possess a functional stinger that is not medically significant to humans. They are generally non‑aggressive, solitary hunters that rely on trap‑jaw mandibles to capture small arthropods. Their tiny size (unknown precisely) makes them excellent escape artists, so fine mesh barriers are essential.
• Common Issues: tiny size makes escape likely without fine mesh barriers., specialized diet may require live prey, but specific dietary preferences are not documented., high humidity needs can lead to mold if ventilation is poor., lack of published data means keepers must observe and adapt.

Housing and Nest Setup

Because little is known about the natural nesting habits of Strumigenys chareta, care recommendations are based on general knowledge of the genus. A humid, naturalistic environment is likely preferred. A Y‑tong (AAC) or plaster nest with a water reservoir can help maintain moisture, but a test tube setup may also work for small colonies. Regardless, all connections must be sealed with fine mesh or cotton to prevent escapes, as the workers are tiny. Avoid acrylic nests, as they do not retain humidity well. Provide low lighting, these ants seem to prefer shaded conditions.

Feeding and Diet

There is no published data on the diet of Strumigenys chareta. Based on the genus, they are thought to be specialized predators of small arthropods such as springtails and mites. Live prey is likely essential, while sugar sources are probably ignored. Offer tiny live prey (e.g., springtails, fruit fly larvae) and observe acceptance. Remove uneaten prey after 24 hours. If the colony is not feeding, try different micro‑prey species.

Temperature and Care

As a tropical species, Strumigenys chareta likely requires warm conditions (roughly 24‑28°C, inferred from origin). Use a small heating cable on one side of the nest to create a gradient. Avoid temperatures below 22°C, as this may slow development. Humidity must be high, keep the substrate moist but not waterlogged. Good ventilation is important to prevent mold. Monitor your colony closely and adjust conditions based on their behaviour, as no specific optimal ranges are known.

Behavior and Temperament

Strumigenys chareta is not aggressive and will flee rather than fight. They hunt alone using their trap‑jaw mandibles. Their tiny size means they are excellent escape artists, use fine mesh (≤0.5 mm) on all openings. They are best suited to keepers who enjoy observing subtle, predatory behaviour rather than large, active foragers. They possess a functional stinger (based on subfamily/tribe), but it is harmless to humans.
