For example try to visit a museum that features insects- several exist in the region, including some that even feature fossil insects. Working with other 4-H members always is a great way to learn more and, as you get further along, you may wish to help some newer members.
Many butterflies feed on nectar from flowers, but some flowers are particularly favored.
Also, caterpillar stages sometimes develop on garden flowers, such as the parsleyworm on parsley or dill that later transforms to the beautiful black swallowtail. 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.
