Rattle Ant - Polyrhachis (Cyrtomyrma) sp., Polyrhachis australis
Ants Tree House
On March 2003 we found a Rattle Ant nest in the front yard of my office. We looked at them everyday. One day, we noticed that the number of ants is reduced. A few days later, all ants were not there, left only the empty nest. So we took the nest home to have a further look.
We believed the ants left the nest could be due to too much of our interruption. The nest was in the middle of the plants. For easier observation, We had removed some of the branches block our vision. Although we did not affect the construction of the ants nest, there were more sun light shined on the nest because of the changes..
The nest are constructed by three leaves and two dead leaves, about 10cm x 4cm in size. When open the nest, I find there was still one ant inside, which is smaller than normal, about 5mm body length.
Building nest - weaving with larvae's silk
Near one of the Rattle Ant colonies, we found two Rattle Ants. One ant was holding a larva, the other pulling out some silks from the larva. There was some silks attaching one leaf from anther leaf. We understood that those ants were just start to build a new room for their colony.
