An insect can be identified with six or eight legs and three sections of the body- head, thorax and abdomen. There are innumerable types of insect existing in this world. However, entomologists have divided them into 30 scientific groups. The groups are further classified into six broad categories.
First category is of flies, which consists of houseflies, stable flies, Tsetse flies and mosquitoes. These insects breed in garbage, manure or accumulated water bodies. They have a pair of wings that help them to fly.
Next category is named as dragonflies, which consist of thin and carnivorous flies living on the other flies. They breed mainly in water bodies.
Other category is of butterflies, which are the most familiar type of insects. They have two large wings that help them in flying flawlessly. Their main source of food is nectar of flowers. Their life cycle consists of four parts- egg, caterpillar, cocoon and adult.
The fourth category of insect is the beetle. They have round shaped bodies and two pairs of wings- the outer pair of wings are harder than the inner one and help them making a protective shell around themselves. Beetles can walk comfortably, unlike other insects. Some beetles are harmless while others may sting.
The next category is of bugs that include water bugs, cicada, bedbugs and stink bugs. Some bugs can only crawl or hop about while others can fly. However, the similarity between different bugs is their ability to penetrate into food to extract its juice.
The last category contains bees, ants and wasps which are commonly witnessed in the environment. These insects have a nature of working in teams. The queen of their community is supposed to lay all the eggs. They have unmatched coordination in collecting food, laying eggs and even attacking enemy or prey. They have a very organized and structured hierarchical system.
