If you live near such areas you should pack along a few flies that imitate each of these insects as well. Terrestrial patterns are all fished the same way . A slight twitch now and then can attract the attention of a trout as well. Fly patterns that imitate the staples of a trout's diet are good patterns to start with in any stream or lake. They are always present and so the fish recognise them as food all year 'round.
