Iridomyrmex bicknelli, commonly known as the black trail ant, is one of the most widespread and recognizable ant species in Australia. These ants are highly adaptable and can thrive in a variety of environments, from urban areas to natural habitats. Known for their timid disposition and non-aggressive nature, they are a beginner-friendly species, ideal for those interested in observing the social behaviors of ants.

Iridomyrmex bicknelli ants are highly adaptable and can be found in various environments across Australia, including urban areas, sandy coastal regions, and native habitats. They are often seen forming large, active trails as they forage for food. Despite their commonality, they are known for their timid nature, unlike many of their more aggressive Iridomyrmex relatives. These ants do not sting or spray formic acid and are not known to bite, making them less of a threat to humans and other animals.
In the wild, Iridomyrmex bicknelli colonies are often polygynous, meaning they can have multiple queens. This contributes to their ability to grow large colonies with very high worker numbers. However, in captivity, they are usually monogynous, with colonies averaging around 10,000 workers. The queens are fully claustral, meaning they do not require food during the initial founding of the colony, relying instead on their body’s fat reserves.
When purchasing an Iridomyrmex bicknelli colony, you will typically receive a healthy queen and a small number of workers, along with a certificate of export and health assurance. This species is particularly well-suited for beginner ant keepers due to its ease of care and rapid colony growth. The ants are small, with queens ranging from 7-10mm and workers from 2-5mm in size.
To successfully maintain an Iridomyrmex bicknelli colony, consider the following care guidelines:
-
Temperature: These ants thrive in a temperature range of 21-26°C in the nest, with the outworld temperature slightly broader, between 18-30°C. They are most active in warmer temperatures.
-
Humidity: Maintain a humidity level of 30-50% in the nest and 40-60% in the outworld to mimic their natural environment.
-
Diet: Iridomyrmex bicknelli ants have a diverse diet that includes liquid sugars like honey water and proteins from insects such as cockroaches, crickets, and mealworms. They can also be fed fruits, vegetables, and other protein-rich foods like cooked chicken without salt.
-
Hibernation: Although hibernation is not strictly necessary, it is recommended to give the colony a rest period from late October to the end of March at a reduced temperature of 15-18°C. During this time, the queen will slow down her egg-laying.
-
Nesting Options: Iridomyrmex bicknelli can be housed in various types of nests, including acrylic nests for easy observation, gypsum nests for moisture control, aerated concrete nests for better airflow, or earth nests to simulate their natural environment. These options allow you to cater to the specific needs and preferences of your colony.
Iridomyrmex bicknelli is an excellent species for ant enthusiasts due to their fast growth, large colony sizes, and fascinating foraging behavior. Whether you are a beginner or an experienced ant keeper, these ants offer an exciting opportunity to observe the intricate social structure and behaviors of a thriving ant colony.
