E.O. Wilson, eminent biologist and the father of biodiversity, called insects “the little things that run the world” because of the many essential ecological roles they play every day. Insects are the most diverse group of animals on Earth and include ants, lady bugs, bees, fireflies, butterflies, dragonflies, grasshoppers, and true flies. Insects can be grouped into three broad categories: pollinators, prey, and ecological balance.
