When we want to get to know an insect, the first thing we do is look at what its body looks like. The body of an insect usually has a head, a thorax and a posterior. On the head, the insect has complex eyes, one or two sets of antennae that help it sense its surroundings, and mouthparts that vary depending on what the insect eats. On its chest, the insect has legs and sometimes wings of different shapes and sizes that help it fly. The rump has organs for reproduction and, in some species, venom glands or something that makes sounds.

Next we look at how insects behave. This can tell us what species it is. For example, how it flies, what it eats, where it likes to be and how it breeds. Some species, like butterflies, are active during the day, while others, like moths, are active at night.

Scientists use special guides to help them identify insect species step-by-step by how they look and behave. These guides can be general for all species or special for certain groups of insects.

There are also advanced methods, such as DNA testing, which shows what kind of insect it is by its genetic code. This method is becoming increasingly popular because it is accurate and can identify even species that are very similar.

Recognising insects is very important. It helps to protect nature, agriculture and fight pests. It allows scientists to see how nature is changing, to identify insects that don't belong here and to study how insects adapt to climate change. If we did not understand how diverse insects are and how to recognise them, we would not be able to protect our natural environment and keep nature healthy and in balance.
