Plagiolepis perperamus

Plagiolepis perperamus

Plagiolepis perperamus is a small, dark brown ant native to the eastern Mediterranean region. Workers measure just 2mm in length with a distinctive trapezoidal head and notably dense, short hairs covering their abdomen (gaster) ^[1]. This species was only formally described in 2018,having been previously confused with the similar Plagiolepis pallescens ^[1]. It belongs to the Plagiolepis schmitziii group, characterized by dense gaster setosity, and is closely related to P. schmitzii though the two species are separated geographically, P. perperamus occupies the Aegean region east to Iran while P. schmitzii lives in North Africa and Iberia ^[1]. Colonies are polygynous (multiple queens) and polydomous (spread across multiple nest sites), making this an unusual species for antkeepers interested in complex social structures ^[1][2].

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Eastern Mediterranean species native to Greece, Turkey, Iran, Cyprus, and Azerbaijan. Found in humid areas overgrown by macchia or forests, nesting in soil beneath rocks. Prefers warm, thermophilous habitats from sea level to about 600m altitude, though recorded up to 1112m. Often thrives in human-modified landscapes including tourist resorts, cities, urban parks, and roadsides ^[1][2][3][4].
• Colony Type: Polygynous (multiple queens in a colony) and polydomous (multiple connected nest sites). This is unusual among common antkeeping species and means colonies can be quite expansive in the wild ^[1][2].
  • Colony: Polygyne
• Size & Growth:
  • Queen: Approximately 4-5mm (estimated based on genus patterns, specific measurements not documented)
  • Worker: Workers 2mm (HL ~0.5mm, HW ~0.47mm) ^[1]
  • Colony: Likely several hundred workers based on similar Plagiolepis species and polygynous colony structure
  • Growth: Moderate, based on typical Plagiolepis development patterns
  • Development: Estimated 6-8 weeks at optimal Mediterranean temperatures (24-28°C), based on genus-level data for related species (Direct development data unavailable for this species, estimate based on typical Plagiolepis growth patterns)
• Antkeeping:
  • Temperature: Keep at 24-28°C, mimicking warm Mediterranean conditions. A heating cable on one side of the nest creates a gradient allowing workers to self-regulate. Room temperature (22-24°C) is acceptable as a starting point ^[3]
  • Humidity: Moderate to high, this species naturally inhabits humid areas with macchia and forest cover. Keep nest substrate consistently moist but not waterlogged. Provide a water tube for drinking access ^[1][2]
  • Diapause: Likely, as a Mediterranean species, probably requires a mild winter rest period around 10-15°C for 2-3 months. However, specific diapause requirements are unconfirmed for this species.
  • Nesting: Soil-nesting species that naturally nests below rocks. In captivity, a Y-tong (AAC) nest with soil or a naturalistic setup with a soil chamber works well. Avoid completely dry conditions, they prefer damp substrate. Provide a layer of substrate at least 1-2cm deep ^[1]
• Behavior: Workers are active foragers, both on the ground and in vegetation (they've been collected from blackberry bushes by beating). They are not aggressive and typically flee from disturbance. Their small size means excellent escape prevention is essential, they can squeeze through tiny gaps. Workers are fast-moving and will readily explore their outworld for food. Colonies are polygynous, so you may see multiple queens coexisting, which is unusual and interesting for antkeepers ^[1][3].
• Common Issues: escape prevention is critical due to their tiny 2mm size, use fine mesh barriers and tight-fitting lids, polygynous colonies may have complex queen dynamics, monitor for aggression between queens during founding, wild-caught colonies may carry parasites that can devastate captive colonies, slow founding phase typical of claustral species, new keepers may lose patience, humidity control is important, too dry and brood dies, too wet and mold becomes an issue

Housing and Nest Setup

Plagiolepis perperamus is a soil-nesting species that naturally builds colonies below rocks in humid areas. For captivity, a Y-tong (AAC) formicarium with a soil chamber works well, or you can use a naturalistic setup with a deep soil layer. The nest should have consistently moist substrate, think damp forest floor, not soggy swamp. Provide a water test tube connected to the nest for drinking access, as these ants will readily use it. Because workers are only 2mm tall, escape prevention must be excellent. Use tight-fitting lids, apply Fluon or similar barrier to the rim, and ensure any air holes are covered with fine mesh. A small outworld (foraging area) is sufficient, these ants don't need massive spaces. Temperature should be kept warm, around 24-28°C, with a heating cable on one side of the nest to create a gentle gradient ^[1][2][3].

Feeding and Diet

Like most Plagiolepis species, P. perperamus is omnivorous with a preference for protein. Workers have been observed foraging in vegetation (blackberry bushes), suggesting they collect honeydew and small insects in the wild. In captivity, offer protein sources like small crickets, flightless fruit flies, mealworms, or other small insects twice weekly. Sugar water, honey, or commercial ant jelly can be offered as a constant energy source. Fresh fruit is sometimes accepted. Because workers are tiny, prey items should be appropriately sized, very small pieces or small insects. Remove uneaten prey after 24-48 hours to prevent mold. A constant sugar source should be available in the outworld ^[1].

Colony Structure and Multi-Queen Dynamics

This is one of the more unusual aspects of P. perperamus for antkeepers, colonies are polygynous, meaning they have multiple queens living together. They're also polydomous, meaning the colony spreads across multiple connected nest sites in the wild ^[1][2]. This is different from most common antkeeping species which are monogyne (single queen). In captivity, you may observe multiple queens coexisting peacefully, which can lead to faster colony growth since all queens lay eggs. However, this also means colonies can become quite large. When starting a colony from a wild queen, you may find multiple foundresses together, this is normal for this species. Monitor initially to ensure queens aren't fighting, though polygynous colonies typically establish peacefully ^[1].

Temperature and Seasonal Care

As a Mediterranean species from Greece, Turkey, and nearby regions, P. perperamus prefers warm conditions. Keep the nest at 24-28°C during the active season. A heating cable placed on one side of the nest creates a temperature gradient that workers will use to self-regulate. During winter, a mild diapause (winter rest) is likely appropriate, reduce temperature to around 10-15°C for 2-3 months. This mimics the Mediterranean winter they experience in their native range. However, specific diapause requirements are not scientifically documented for this species, so observe your colony's behavior. If they remain active at room temperature year-round, they may not require strict hibernation. The species has been recorded from sea level to over 1100m altitude, suggesting some flexibility, but they clearly prefer warm habitats ^[3].

Growth and Development

Specific development timeline for P. perperamus has not been documented in scientific literature. Based on typical Plagiolepis genus patterns and related species, expect approximately 6-8 weeks from egg to first worker at optimal temperatures (around 26°C). The first workers (nanitics) will be smaller than mature workers. As a polygynous colony, growth may be faster than single-queen species since multiple queens can lay eggs simultaneously. Colonies likely reach several hundred workers in captivity under good conditions. Be patient during the founding phase, claustral queens seal themselves in and can take weeks to produce their first workers without leaving the nest to forage. Avoid disturbing the founding chamber during this critical period ^[1].
