Ooceraea coeca

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Sri Lanka (Ceylon), found in forest floor environments ^[1][3].
• Colony Type: Colony structure is unconfirmed. No specific data available.
• Size & Growth:
  • Queen: Size data unavailable ^[4]
  • Worker: Size data unavailable ^[4]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown, no direct measurements exist. (No specific development data exists for O. coeca.)
• Antkeeping:
  • Temperature: Based on tropical origin, keep warm around 24-28°C, but no specific data ^[4].
  • Humidity: Keep nest substrate consistently moist but not waterlogged, as Dorylinae often prefer humid conditions ^[4].
  • Diapause: Unknown, Sri Lanka has tropical climate with minimal variation, so diapause may not be necessary.
  • Nesting: Use humid nests like Y-tong or plaster. Provide dark, enclosed spaces for their subterranean lifestyle ^[4].
• Behavior: Likely cryptic and secretive, avoiding light. Based on Dorylinae patterns, may be predatory but not aggressive towards humans ^[4].
• Common Issues: blindness makes them sensitive to light, keep nesting areas dark., high humidity requirements can lead to mold if ventilation is poor., escape prevention is important, they are small but persistent explorers., no established feeding protocols, experimentation needed., very rare in the hobby with almost no keeper experience.

Appearance and Identification

Ooceraea coeca workers are small ants, but specific size data is unavailable ^[4]. Their most distinctive feature is their complete lack of functional eyes ^[1][3]. Body is foveolate, meaning pitted ^[1][3]. Antennae have 11 segments ^[1][2][3]. Postpetiole is almost as long as wide ^[1]. Pronotum has a distinct ridge and is slightly convex dorsally ^[2][3].

Natural History and Distribution

Ooceraea coeca is endemic to Sri Lanka ^[1][2][3]. It likely inhabits forest floor environments, foraging in dark, humid microhabitats ^[1][3].

Housing and Nest Preferences

Based on their blind, subterranean nature, provide dark, humid nests like Y-tong or plaster ^[4]. Keep nesting areas dark and use simple outworlds since they are not strong climbers.

Feeding and Diet

Feeding protocols are not established. Based on Dorylinae patterns, they may be predatory on small invertebrates ^[4]. Offer small live prey and observe acceptance.

Temperature and Humidity Requirements

No specific data, but as tropical ants, keep warm and humid ^[4]. Maintain temperatures around 24-28°C and keep substrate moist but not waterlogged.

Behavior and Temperament

Likely cryptic and secretive, avoiding light ^[4]. Based on Dorylinae patterns, they may raid other colonies but are not aggressive towards humans.
