Plectroctena lygaria

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Ivory Coast, West Africa, in forest-savannah mosaic environments ^[3].
• Colony Type: Colony structure is unconfirmed, no specific data on queen number or social structure.
• 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: Estimated up to several hundred workers, based on genus patterns
  • Growth: Moderate, inferred from related Ponerinae species
  • Development: Estimated 6-10 weeks at tropical temperatures, based on related species patterns (Development time is estimated, specific data for P. lygaria is unavailable)
• Antkeeping:
  • Temperature: Keep warm year-round, roughly 24-28°C, inferred from tropical habitat ^[3]
  • Humidity: Keep substrate consistently moist but not waterlogged, based on forest-edge habitat
  • Diapause: No, tropical species does not require hibernation, inferred from geographic range
  • Nesting: Use test tube setup for founding, once established, Y-tong or plaster nests with small outworld, standard practice for Ponerinae
• Behavior: Plectroctena lygaria is a specialized egg predator, hunting myriapod and millipede eggs ^[1][2]. As Ponerinae, they have a functional sting for defense. Workers forage individually or in small groups and are moderately aggressive when defending the nest.
• Common Issues: specialized diet may refuse standard foods, live prey is essential for colony growth, temperatures below 22°C can weaken or kill the colony, escape prevention needed, they can climb smooth surfaces, wild-caught colonies may carry parasites difficult to treat, founding phase may take months, patience required

Housing and Setup

For a newly caught queen, use a standard test tube setup with water and cotton plug. Place in a dark, quiet location at 24-28°C. Once the colony reaches 30-50 workers, move to a Y-tong or plaster nest with a small outworld. Use barrier methods like fluon on rims to prevent escapes. Provide a heat source if room temperature is below 24°C. ^[3]

Feeding and Diet

This species is a specialized egg predator, hunting myriapod eggs and storing millipede eggs ^[1][2]. In captivity, offer live small prey like fruit flies, small crickets, and mealworm pieces. Sugar water or honey can be offered occasionally, but protein from live prey is essential. Feed every 2-3 days, removing uneaten prey after 24 hours.

Temperature and Seasonal Care

As a tropical West African species, keep temperatures between 24-28°C year-round. No hibernation is needed. If room temperature is below this range, use a heating cable or heat mat to create a gradient. Avoid prolonged temperatures below 22°C.

Behavior and Defense

Plectroctena lygaria has a functional sting as part of the Ponerinae subfamily. Workers hunt individually or in small groups and defend the nest aggressively when disturbed. They are not typically aggressive toward humans unless threatened.

Colony Development

Founding behavior is unconfirmed, no specific data on whether queens are claustral or semi-claustral. Expect a slow founding phase, be patient and provide regular small prey. Growth rate is moderate once workers emerge.
