Plagiolepis regis

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Palaearctic region, recorded from Kazakhstan, Azerbaijan, and Dagestan (Russia). Habitat preferences are not documented ^[2][3].
• Colony Type: Unconfirmed, colony structure has not been studied. The uncertain parasitic status means we do not know if this species can found colonies independently.
• Size & Growth:
  • Queen: Approximately 4-5 mm, inferred from Plagiolepis genus patterns ^[1].
  • Worker: Approximately 1.5-2.5 mm, inferred from Plagiolepis genus patterns ^[1].
  • Colony: Unknown, no colony size data available.
  • Growth: Unknown
  • Development: Estimated 4-6 weeks, inferred from typical Plagiolepis development ^[1]. (Development timeline is inferred from genus-level data.)
• Antkeeping:
  • Temperature: Start around 20-24°C and observe colony activity. No specific thermal studies exist for this species ^[1].
  • Humidity: No specific humidity data available. Plagiolepis species typically prefer moderate conditions, avoid both excessive dampness and dryness ^[1].
  • Diapause: Unknown, no documented overwintering requirements. Based on temperate distribution, some form of winter rest is likely but unconfirmed ^[1].
  • Nesting: Natural nesting preferences are undocumented. Most Plagiolepis species nest in soil under stones or in small cavities. A small test tube setup or Y-tong nest with narrow chambers would be appropriate given their tiny size ^[1].
• Behavior: Behavior is not documented in available literature. As a Plagiolepis species, they are likely relatively docile and not aggressive. Their tiny size means excellent escape prevention is critical. The uncertain parasitic status means their founding behavior and colony dynamics are unclear ^[1]. This species is listed as Vulnerable on the IUCN Red List, so it should not be released and ethical sourcing is important ^[4].
• Common Issues: this species has almost no documented care information, keeping it successfully would require experimental approach ^[1]., escape prevention is critical due to their very small size ^[1]., the uncertain parasitic status means we don't know if standard founding methods will work ^[1]., no confirmed diet information, related species typically eat honeydew and small insects ^[1]., this species is listed as Vulnerable on the IUCN Red List, so it should not be released and ethical sourcing is a concern ^[4].

Taxonomic History and Nomenclature

Plagiolepis regis was originally described by Karavaiev in 1931 from Kazakhstan as Plagiolepis (Plagiolepis) regis ^[1]. The species was later moved to the genus Aporomyrmex by Faber in 1969,but was returned to Plagiolepis by Dlussky and Zabelin in 1985 ^[1]. This taxonomic shuffling reflects historical confusion around its placement.

The Social Parasite Question

Plagiolepis regis has been considered a potential social parasite based on morphological similarity to Plagiolepis ampeloni, a known workerless inquiline ^[1]. However, P. regis differs in having a worker caste, suggesting it may be free-living, but this remains unconfirmed until nests are examined ^[1].

Distribution and Conservation Status

Plagiolepis regis has a limited distribution in the Palaearctic region, recorded from Kazakhstan (type locality), Azerbaijan, and Dagestan in Russia ^[2][3]. It is listed as Vulnerable (VU) on the IUCN Red List ^[4]. This vulnerable status means wild-caught colonies should be approached with caution, and established captive colonies should not be released.

Keeping Plagiolepis regis - A Note of Caution

This species has no documented captive care, and its parasitic status is unresolved. If obtained, expect an experimental approach. Start with standard Plagiolepis care: small test tube nests, moderate temperature around 22°C, and offer sugar water and small protein sources. Document everything carefully. Do not release this species due to its vulnerable status and uncertain ecological role ^[1][4].
