If you experience one of these miserable days when early season hatches can t escape from the surface you ll never forget it. In mid-May a transformation takes place with the hatches. Anglers begin seeing other hatches the March brown and the sulphur in the East and Midwest and the pale morning dun in the West. Contrasted with the gray hatches of April all three are cream to yellow insects. Hatches at this time also begin appearing at times other than the afternoon.
Sulphurs often appear just as dusk approaches.
Don t forget get to try wet flies at that time of year. Just think for a moment what happens to all the dazed duns floating past you. After riding on the surface through several pools and riffles many of these dazed duns go under the surface and are taken underneath by trout. Classic wet fly patterns copying these hatches often work well. Then look for them in April and May most often in the afternoon.
