There are many flying insects that are beneficial to your home landscape. Butterflies, dragon flies, and ladybugs are flyers that everyone loves and considers special.

The honeybee and the bumblebee are common visitors to the flower and vegetable garden and they do much of the pollination work needed by those plants. For more information see Bees As Pests.
