A number of them are predators, like lady beetles which live by feeding on pestiferous aphids. Others, like certain wasps, may be parasitic on pest insects. Still others, such as the honey bees, act as pollinators of crops and also provide us with honey. Many insects are responsible for the decomposition of plant and animal matter. Termites are an example of this.
Insects are also food for other creatures such as fish, frogs, birds and bats.
Some keep weeds in check. Our life would be much more difficult without insects. This site was developed for the Arizona Cooperative Extension , College of Agriculture , The University of Arizona . The University of Arizona. All contents copyrighted.
