Plagiolepis atlantis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: North Africa (Algeria, Tunisia) and eastern Mediterranean (Turkey). They nest in soil beneath stones in humid areas overgrown with macchia or forest vegetation ^[1].
• Colony Type: Polygynous, colonies contain multiple queens working together ^[1].
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements in research context.
  • Worker: Size data unavailable, no total length measurements in research context.
  • Colony: Up to several hundred workers, estimated from polygynous structure ^[1].
  • Growth: Moderate
  • Development: Estimated 6-8 weeks at optimal temperature, inferred from related Plagiolepis species. (Development time is temperature-dependent.)
• Antkeeping:
  • Temperature: Keep warm and stable, roughly low-to-mid 20s°C, inferred from Mediterranean climate.
  • Humidity: Keep the nest substrate consistently moist but not waterlogged, as they inhabit humid areas ^[1].
  • Diapause: Unknown, no data on diapause requirements.
  • Nesting: Soil-nesting species that naturally nests beneath stones ^[1]. In captivity, use moist substrate with flat stones or a Y-tong/plaster nest.
• Behavior: Workers are non-aggressive and primarily forage for honeydew and small prey. Their extremely small size means escape prevention is critical, they can squeeze through tiny gaps. Colonies are polygynous, which supports larger colony sizes ^[1].
• Common Issues: escape prevention is critical due to their extremely tiny size, use fine mesh barriers and tight-fitting lids., polygynous colonies may have queen competition during founding, monitor when introducing new queens., small colony size at founding makes them vulnerable to stress and dehydration., humidity management is tricky, too wet causes mold, too dry kills brood., wild-caught colonies may carry parasites that can decimate captive colonies.

Housing and Nest Setup

You need to house Plagiolepis atlantis carefully due to their extremely small size. These tiny ants can escape through gaps that would hold back much larger species. Use test tubes with tight cotton or apply fluon barriers on the rim. For the nest, a naturalistic setup with moist substrate (a mix of soil and sand) beneath flat stones simulates their natural environment ^[1]. Alternatively, a Y-tong or plaster nest with very small chambers can work, but ensure passages are appropriately sized. The nest area should stay humid but not wet, with some drier areas available for self-regulation.

Feeding and Diet

You should offer omnivorous diet to Plagiolepis atlantis. Workers readily collect honeydew from aphids and will drink sugar water or honey diluted with water. For protein, provide tiny prey items like fruit flies or small mealworms. Larvae are omnivorous ^[2], so both sugar and protein sources support brood development. Feed small amounts of sugar water every few days and protein once or twice weekly. Remove uneaten prey within 24 hours to prevent mold.

Temperature and Seasonal Care

You should keep these ants at room temperature or slightly above, roughly 20-26°C, inferred from their Mediterranean origin. They can tolerate brief cooler periods but prolonged cold slows brood development. During winter, a mild hibernation period may benefit colony health, but no specific data exists on diapause requirements. Avoid very cold temperatures as they are not adapted to harsh winters.

Colony Structure and Multi-Queen Care

You are keeping a polygynous species, meaning colonies naturally have multiple queens ^[1]. This supports faster initial growth but requires attention to colony harmony. When starting a colony, you may keep multiple founding queens together, but separate them if they fight. Established polygynous colonies are generally stable, with queens tolerated by workers.

Escape Prevention

You must prioritize escape prevention due to their extremely tiny size. Workers can squeeze through standard test tube cotton, tiny gaps in lids, and fine mesh. Apply fluon to all enclosure rims and use containers with tight-fitting lids. Check enclosures daily and seal any gaps immediately. This species will escape if given half a chance.
