Dragonflies can reach wingspans of 20 - 190 mm. Their bodies vary widely in terms of colouration. The head is completely separated from the chest and is therefore very flexible. Between the very large compound eyes are 3 simple eyes. The rear chest segments (mesothorax and metathorax) are strongly built.

They can use their two nearly identical pairs of large wings independently in flight and can therefore abruptly change direction. They can hover at one point in the air and even fly backwards. Flight speeds of up to 50 km/h are not uncommon. The abdomen is very long and thin and has a stabilizing effect in flight.

Dragonflies prefer to live near standing or flowing water. Many dragonfly species can be found in parks and gardens in areas inhabited by people.
