Insects create the biological foundation for all terrestrial ecosystems. They cycle nutrients, pollinate plants, disperse seeds, maintain soil structure and fertility, control populations of other organisms, and provide a major food source for other taxa.

What would happen if there were no bugs?

Many insects use wings to fly around. ... Some animals, like small birds, frogs and other reptiles and amphibians, survive almost entirely on an insect diet. If there were no bugs for these animals to eat, they would eventually die off. That, in turn, would eliminate the food source for other animals farther up the chain.
