Fish nymphs dead drift lifting them off the bottom at the end of the float. Look for the biggest trout in the best feeding lanes. Emerger Fish the same as with nymphs. Dun Since other baetis species may be emerging simultaneously, a range of imitations should be carried. At least two body colors (light olive and darker olive) and sizes ranging from #16 to #20. Catch a natural to determine positively the correct size and color. Vagans hatching in the cool early season have trouble getting off the water after emergence. Therefore, dun patterns floated dead drift for long distances is the best imitation. Spinner Oviposting adults not sought by the trout maybe because of other species on the water.
