Species Overview

Ooceraea biroi, commonly known as the Clonal Raider Ant, is an extraordinary species that defies conventional ant biology. Unlike most ant species, O. biroi lacks a queen caste—every worker is a fertile female capable of reproducing through thelytokous parthenogenesis, resulting in genetically identical offspring. Measuring 2.5–3 mm in length, these small reddish-brown ants possess slender heads and 9-segmented antennae. Their unique reproductive system and highly synchronized colony cycles make them a fascinating model organism for both hobbyists and researchers studying social evolution.

Natural Habitat & Behavioral Characteristics

Native to forest leaf litter and soil layers across Southern China and Southeast Asia, Clonal Raider Ants exhibit nomadic lifestyle patterns synchronized with their brood development. Colonies alternate between two distinct phases: an active raiding phase and a stationary brood-care phase. During the raiding phase, they cooperatively hunt for small arthropods, displaying remarkable coordination for such tiny ants. Instead of traditional nuptial flights, new colonies form through fission, where groups of workers and brood separate to establish new nests. Their pupae secrete nutrient-rich fluids, functioning as a nutritional exchange system comparable to “milk” in mammals—a rare and captivating adaptation among ants.

Comprehensive Keeping Guidelines

Optimal Habitat Configuration:

• Nest Type: Simple plaster nests or test tube setups; minimal space is required due to their small size.
• Temperature: Maintain between 22–26°C for ideal brood development.
• Humidity: Keep moderate humidity levels (60–75%) while avoiding excessive moisture.
• Foraging Area: Compact, escape-proof setups with smooth barriers, as they have limited climbing ability.

Nutritional Requirements & Feeding Protocol:

• Protein Sources: Insect prey such as fruit flies or small crickets, especially during their raiding phase.
• Supplemental Nutrition: Sugar water or diluted honey to maintain energy levels.
• Feeding Schedule: Synchronize feedings with their brood cycle—offer more protein during larval stages.

Special Care Considerations:

• Colony Foundation: Colonies can thrive even with a small group of workers (6+ individuals).
• Reproductive Management: Understanding their clonal reproduction ensures stable, predictable colony growth.
• Behavioral Observation: Excellent species for studying primitive social organization and division of labor.
• Experience Level: Suitable for beginners to advanced keepers, especially those interested in scientific observation.

Important Acclimation Information

New colonies may temporarily pause their brood cycle during transport. Allow 1–2 weeks for stabilization in a quiet, consistent environment with proper temperature and humidity. Due to their clonal nature, colonies typically recover rapidly and resume synchronized behavior once settled.

Responsible Keeping Notice

This species provides an exceptional opportunity to observe evolution and social behavior in action. However, it requires responsible containment. Never release colonies into non-native environments, and always adhere to local regulations regarding ant keeping.
