Platythyrea lamellosa

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to southern Africa, including South Africa, Botswana, Namibia, Zimbabwe, Angola, and the Democratic Republic of Congo ^[1]. Found primarily in woodland habitats, but also in sedgeland-herbland, forest, thicket, and shrubland areas ^[2], with decreasing abundance above 1200m elevation ^[3].
• Colony Type: Queenless colony, reproduction is handled by gamergates (mated workers), with a single gamergate per colony ^[4].
• Size & Growth:
  • Queen: N/A, queenless species (reproduction by gamergates)
  • Worker: Size data unavailable, inferred from Platythyrea genus (~5-7mm) ^[1]
  • Colony: Up to approximately 200 workers ^[4]
  • Growth: Moderate
  • Development: Unknown, no specific development data available for this species. (Development timeline unconfirmed, based on typical Ponerinae patterns, it may take several months.)
• Antkeeping:
  • Temperature: Temperature needs are unclear, start around 22-26°C and observe, based on their African distribution ^[1].
  • Humidity: Provide a humidity gradient based on woodland habitat, keep nest substrate moderately moist but not waterlogged ^[2].
  • Diapause: Unknown, no specific data on diapause requirements for this species.
  • Nesting: In nature, they nest under stones and in rotting wood ^[1]. In captivity, use Y-tong (AAC) or plaster nests with moderate moisture, and provide a small outworld for foraging.
• Behavior: Based on Ponerinae patterns, they are generally peaceful but may bite if threatened. Escape risk is moderate due to their size, use standard barrier methods ^[1].
• Common Issues: establishing colonies is difficult because you must acquire an already-reproducing colony with gamergates ^[4], colony growth is moderate, with maximum size around 200 workers ^[4], limited availability in the hobby since they cannot be caught as founding queens, may be sensitive to excessive moisture, provide a humidity gradient ^[2]

Understanding Queenless Biology

Platythyrea lamellosa lacks a queen caste entirely. Reproduction is handled by gamergates, workers that have mated and can lay eggs ^[4]. This is a single gamergate species, meaning typically only one mated worker per colony reproduces ^[4]. Virgin workers develop oocytes but do not lay eggs, regulation happens at the oviposition level ^[5]. You cannot start a colony with a queen because one does not exist. Instead, you must acquire an established colony with mated, reproductive workers.

Nest Preferences and Housing

In the wild, Platythyrea lamellosa nests under stones and in rotting wood in woodland habitats ^[1]. For captive care, use a Y-tong (AAC) nest or plaster formicarium. Provide a humidity gradient based on their natural habitat, keep the nest substrate moderately moist but not waterlogged ^[2]. A small outworld of about 10x10cm provides space for foraging. Since they are moderate escape risks, standard barrier methods like fluon on container edges work adequately.

Feeding and Diet

As Ponerinae ants, Platythyrea lamellosa are predators that hunt small invertebrates ^[1]. In captivity, offer small live prey such as fruit flies, small crickets, or mealworms 2-3 times per week. Remove uneaten prey after 24-48 hours to prevent mold. They may occasionally accept sugar water or honey, but protein-rich prey should form the main diet.

Temperature and Seasonal Care

Temperature needs are unclear, start around 22-26°C and observe colony activity. Based on their African distribution, they prefer warm conditions. A heating cable on one side of the nest can create a gradient. During cooler months, room temperature (around 18-20°C) may be sufficient, they do not require true hibernation. Avoid temperatures below 15°C for extended periods.

Colony Dynamics and Behavior

Workers divide labor within the colony, with different individuals handling foraging, brood care, and nest maintenance ^[5]. The single gamergate is responsible for egg-laying ^[4]. Colonies remain relatively small, with up to 200 workers ^[4]. Workers are active foragers that hunt small prey, and colonies are generally peaceful.
