Some bite and sting, and some people are allergic to them. Other insects are injurious to our agricultural crops, food products, clothing, and wooden buildings. So far human beings have had only partial success in defending themselves against insects. Beneficial insects include bees, wasps, flies, butterflies, moths, and others that pollinate plants. Many fruits, including oranges, apples, strawberries and grapes depend on insect pollinators for the production of seeds.
Some insects provide humans with products such as honey, bees wax, shellac, and silk.
Some help keep the landscape clean by feeding on animal wastes and dead animals, or the remains of dead plants. Insects that live in the ground enrich the soil with their waste products and dead bodies. Many insects are helpful because they are predators and feed on harmful insects that destroy crops. . All insects form part of the great web of life that includes human beings and all other living things.
