The angler who chases panfish with a fly has a mind-numbing variety of flies to choose from. Traditional dry flies, hair bugs, foam bugs, and poppers will all work if the fish are looking up. As we move into the spring and summer, terrestrial insects become an essential food source on the ponds and small lakes that I fish near home. The shorelines of these bodies of water are buzzing with flying and crawling terrestrial insects and many of them find their way into the water.
