Insects represent the most numerous class of animals. We consider ourselves as masters of the planet, but the tiniest creature, smaller than a nail can kill us. There is over a million described insect species which is more than 2/3 of total number of all animal species in this planet.

They are very different in their appearance and way of life: head, stomach and chest. Some of them are useful for a man because they pollinate plants, while others are vermin or spread contagious disease among people and animals. Even though most insects which we encounter are harmless, some of them are extremely dangerous for people and their sting can cause various allergic reactions and infections. Each year all over the world over a million people die from bites from a tse-tse fly or malaria which is spread by malaria mosquitoes. From million of insects that live on our planet look at which 10 are the most dangerous.
