Yes, as they provide many beneficial functions. A couple of examples are the pollination of food crops, and as important important members of the food chain. There are many insects that are beneficial to both humans and plant life. For example: * Some insects are beneficial to farmers and gardeners since they eat other insects that are harmful to plants. One example is the ladybug; they eat aphids that can kill many plants. Some farmers have begun "going green" in raising their crops by bringing in the insects that eat the ones that harm plants. This allows them to raise crops with out harmful poisons. * Dragonflies eat mosquitoes, which we all know are harmful to both humans and animals.
No, if anything they are beneficial since their diet is insects.
