Although many people don’t like to consider it, a bug habitat is an important and vital role in the circle of life. While we may consider them to be pesky irritants, insects do carry out extremely beneficial functions within the environment that would suffer without their presence.Insects comprise a very large life form; in fact, there are more insects on the earth than humans. The exact number of different types of insects is unknown; however; a fairly accurate estimate by entomologists gives credence to the fact that there exists on earth over eight million different species. This number is mind boggling, but consider the fact that insects live in every single type of environment, no matter how harsh. It is true, though, that the majority of them live within the warm, moist atmospheres of tropical climates.
