Keep records of the flowers butterflies most often use and plan a garden to attract these insects. Several insects are important as biological controls of pests. Lady beetles and praying mantids are good examples. Spend some time observing them and watch what they eat, how active they are, and where they occur most commonly. You may want to take your studies indoors, rearing the insects for awhile so you can make better observations.
Honeybees are very important in the pollination of crops.
They also produce honey, beeswax and other products. If you live in an area where bees are used to pollinate crops talk to the growers about the benefits that they get from these helpful insects. If you can find a local beekeeper, try to spend some time with him to learn about the practice of apiculture -the keeping of bees. Insects can be good indicators of the quality of water. At several points in a river collect the aquatic insects that live there.
