Ants look different when they are in a certain stage of their life cycle. They start with eggs, larvae, pupa, and then adult. When they enter the adult stage, they assume different roles in the nest. Ants have different sizes and colours and these are factors that can help you know the specific role of an ant inside the nest. Furthermore, identifying household ants from those living outdoors plays an important role to get the right treatment.
Their bodies are segmented in head, thorax, and abdomen. The species of ants vary with their body shapes, colour, and sizes. Though most ants are considered pests, there are some that are beneficial while some are considered slightly annoying.
