The pale morning dun (Ephemerella excrucians) is the most prolific mayfly in the West, & possibly the most important in
In NE
Washington we usually begin to see PMD’s on the warmer days toward
the end of May, with hatches peaking about late June & then lasting well
into July. During the peak season, the river back-eddies hold rafts of sedges
peppered with mayflies, making it seem hopeless to drift a dryfly with so many
naturals clogging the eddy lines. PMD’s emerge in waves, as if with one mind,
cuing trout onto the pulse. Pulse & pause. During the
pauses, trout turn their
attention to the stuff floating on top, or very near the top, displaying a
preference for the small mayflies, PMD’s & the very similar western red quills (Rhithrogena undulata), scattered through the more abundant spent sedges. Trout will nose the sedges aside & eat a mayfly, or an imitation of
one, provided it’s the right size & exhibits a sexy profile (not too fat) however splayed.
This version simulates the
coloration of an adult pale morning dun or red quill, & tied in #12-#18 it
will cover some other mayfly species as well. I fish it in & just under
the surface film, or spritzed with a dressing to float on top.
