Solenopsis condei

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Known only from the type locality in Espírito Santo, southeastern Brazil ^[2][3]. Natural habitat is not recorded but likely tropical or subtropical forest, based on the region.
• Colony Type: Unconfirmed, no specific data available on social structure. Inferred patterns from the genus Solenopsis suggest possible single-queen colonies, but this is uncertain.
• Size & Growth:
  • Queen: Size data unavailable, inferred from small Solenopsis species as approximately 4–6 mm total length
  • Worker: Size data unavailable, inferred from small Solenopsis species as approximately 1.5–3 mm total length
  • Colony: Likely small colonies, probably up to a few hundred workers at maturity (inferred from related thief ants)
  • Growth: Moderate (based on inferences from similar small Solenopsis species)
  • Development: Estimated 5–8 weeks at 24–28°C (inferred from related species) (Development timeline is not confirmed for S. condei and is based on genus-level patterns.)
• Antkeeping:
  • Temperature: Maintain 24–28°C (75–82°F) year-round, reflecting their tropical Brazilian origin. Provide a slight gradient to allow self-regulation.
  • Humidity: Moderate to high, keep nest substrate moist but not waterlogged. Their natural environment is likely a humid forest floor.
  • Diapause: Unlikely, as a tropical species, they probably do not require a winter diapause. Keep temperatures consistent year-round.
  • Nesting: Likely nests in soil or under stones in shaded forest areas. In captivity, a small test tube setup or mini formicarium with moist substrate works well. Provide tight chambers scaled to their tiny size.
• Behavior: Shy and secretive, workers spend most time hidden inside the nest. They are not aggressive and have a functional stinger (typical of Solenopsidini) that is rarely used against humans due to their tiny size. Escape prevention is critical because they can squeeze through very small gaps. Foraging likely occurs at night or in low light.
• Common Issues: tiny size makes escape prevention critical, use fine mesh barriers and seal all gaps, limited scientific data means care is based on genus inferences rather than species-specific research, small colony size makes them vulnerable to disturbance, handle gently, especially during founding, humidity control is important to prevent desiccation in small setups, wild-caught colonies may carry parasites or diseases, observe quarantine before adding to existing setup

Housing and Nest Setup

Solenopsis condei is tiny, so housing must be appropriately scaled. A small test tube with a water reservoir works well for founding colonies. As the colony grows, move them to a small formicarium or mini Y‑tong nest with snug chambers. Keep the nest substrate consistently moist but not waterlogged. A thin layer of substrate (1–2 cm) is enough. The outworld should be small and simple to reduce the chance of losing workers. Escape prevention is essential, use fine mesh on ventilation holes and seal any gaps around tubing.

Feeding and Diet

Like other small Solenopsis, S. condei is likely omnivorous. Offer small live prey such as springtails, fruit flies, or tiny crickets. They may also accept sugar water or honey water, though acceptance varies. Feed protein every 2–3 days and remove leftovers promptly to prevent mold. Sugar sources should be removed within 24–48 hours. A varied diet supports colony health. If they do not take sugar, focus on live prey.

Temperature and Seasonal Care

As a species from southeastern Brazil, S. condei needs warm conditions year‑round. Keep temperatures between 24–28 °C (75–82 °F) for optimal activity and brood development. You can use a heating cable on one side of the nest to create a warm zone (around 28 °C) with cooler areas (24 °C) so ants can self‑regulate. No hibernation or diapause is needed. Avoid temperatures below 20 °C or above 32 °C.

Behavior and Colony Dynamics

This is a shy, secretive species. Workers are small and often overlooked. They are not aggressive and possess a functional stinger (as is typical for Solenopsidini) that they rarely use on humans due to their size. Colonies grow slowly but steadily when conditions are right. The founding method is unconfirmed, but based on typical Solenopsis patterns the queen may seal herself in to raise the first workers without leaving to forage. Expect colonies to stay relatively small (probably under 200 workers at maturity). Minimise disturbances, especially during founding.
