Plagiolepis abyssinica

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Afrotropical region, Eritrea, Ethiopia, and Saudi Arabia. They nest in partially rotting wood ^[2][1].
• Colony Type: Unknown, queens and males have not been described, so colony structure is unconfirmed ^[2].
• Size & Growth:
  • Queen: Unknown, queens have not been described ^[2].
  • Worker: 1.2 mm total length ^[1].
  • Colony: Unknown, no colony size data available.
  • Growth: Unknown, no development data exists.
  • Development: Unknown, no direct data available. (Based on related Plagiolepis species, development may take 4-8 weeks at warm temperatures, but this is unconfirmed.)
• Antkeeping:
  • Temperature: Based on their Afrotropical distribution, temperatures around 24-28°C are likely suitable ^[1].
  • Humidity: Keep nest substrate consistently moist but not waterlogged, as they nest in rotting wood ^[2].
  • Diapause: Unknown, no data on overwintering. Given Afrotropical distribution, they likely do not require diapause ^[1].
  • Nesting: Naturally nest in partially rotting wood ^[2]. In captivity, use small wooden nests or Y-tong with narrow chambers ^[2].
• Behavior: Workers are very small (1.2 mm) and active, making escape prevention critical ^[1]. They are likely generalist foragers, similar to other Plagiolepis species. Workers have large eyes, which may aid visual navigation ^[1]. Not known to be aggressive.
• Common Issues: tiny size makes escape prevention critical, they can squeeze through standard mesh, no described queens means colonies cannot be established from scratch, only wild-caught queens can start a colony, all care information is estimated due to lack of species-specific data, slow growth is likely due to small size, risk of colony collapse from stress, wild-caught colonies often struggle in captivity

Understanding the Challenge

Plagiolepis abyssinica is challenging to keep because queens and males are undescribed ^[2]. This means you cannot establish a colony from scratch, only wild-caught queens can start a colony. The lack of described sexuals means we know little about reproduction, nuptial flight timing, or colony founding behavior. Everything is estimated from related Plagiolepis species and their Afrotropical distribution ^[1].

Housing and Escape Prevention

Workers measure 1.2 mm, so escape prevention is critical ^[1]. Use fine mesh (at least 0.5mm) on ventilation holes, seal connections with fluon, and check for gaps regularly. For founding colonies, a test tube setup works, but modify the cotton plug tightly. For established colonies, use small wooden nests or Y-tong with narrow chambers (2-3mm wide) ^[2].

Temperature and Heating

Given their origin in Eritrea, Ethiopia, and Saudi Arabia, aim for 24-28°C ^[1]. Provide a temperature gradient with heating on one side. Room temperature may be acceptable but growth slower. Avoid temperatures above 32°C to prevent stress.

Feeding and Diet

Diet is unknown for this species. In captivity, offer sugar water and small protein sources like fruit flies, but observe what the colony accepts ^[2]. Feed small amounts every 2-3 days and remove uneaten food to prevent mold.

Nesting Preferences

Naturally nest in partially rotting wood ^[2]. In captivity, provide small wooden formicarium or Y-tong with damp substrate. Chambers should be very small,2-3mm deep, to match their size ^[2].
