All of them. Insects make the world go 'round. They pollinate plants (particularly agricultural crops), dispose of dead things and provide food for countless other animals (and even for plants). There are literally more than a million described different kinds, and more are still being discovered and classified. Some estimates list the total number of different types as 20 to 30 million different critters, and even if that number is high, there are many, many more yet to be included in the literature.
