Larva hatches out of the egg as a white grub which is narrower towards the head. They are fed by the adults.
The larva pupates and appears creamy-white, looking similar to an adult. Sometimes they have a protective silk cocoon around them.
The adult emerges with the three defined body sections: head, thorax and abdomen.
The length of time between the egg stage and ants emerging as adults can take 6 weeks or more; it depends on a variety of factors such as the species of ant, the temperature and the availability of food.
Fertilised eggs become female, unfertilised become males.
Black House Ants nest under bark or in decaying timber.
They infest homes and buildings in search of food and water; they are especially attracted to sweet foods but also eat the honeydew which is secreted from sap-sucking insects.
