Right now terrestrial patterns get you the best action on most streams.  With cooling and shorter days the Firehole River will offer better action from such as BWO and cadds activity.  Trico spinner falls bring action on all Fall River Basin streams.  Brown trout are beginning to forage before spawning runs.  So be sure to have streamer patterns in your fly box.  As we move through autumn, rely more and more on them to bring action.
