Stings and bites from insects are common. They often result in redness and swelling in the injured area. Sometimes a sting can cause a life-threatening allergic reaction.
Arthropods are insects that live primarily on land and have 6 legs. They dominate the present-day land fauna. They represent about three-fourths of known animal life. In fact, the actual number of living species could range from 5-10 million.
The orders that contain the greatest numbers of species are Coleoptera (beetles), Lepidoptera (butterflies and moths), Hymenoptera (ants, bees, wasps), and Diptera (true flies).
Insects do not usually attack unless they are provoked. Most bites and stings are defensive. The insects sting to protect their hives or nests.
