Brown Drakes - (Ephemera simulans) - Nymphs and Emergers

Nymphs:
The “Brown Drake” nymphs are burrowers that spend most of their life in their burrows.
The come out primarily to feed at night. When it is time for the hatch, the nymphs come
out of their burrows and accent to the surface hanging just below the surface skim.
There they shed their nymphal shuck. They usually drift only a short distance before
flying away. Hatches normally start occurring just before darkness approaches. The
hatch last for just a few days.  

Presentation:
Fishing imitations of the Brown Drake nymphs when there is no hatch occurring is not
very productive in our opinion. It is productive when the hatch begins. When fishing a
brown drake nymph imitation you should try to imitate the erratic actions of the nymphs.
Weighted nymphs are best fished by slowly stripping the line in small, short darts
across the stream bottom.  This may be tested by trail and error during the periods of
time our hatch charts show that hatches should occur, or as soon as you determine
that the brown drakes duns have started to hatch.

Emerger:
It is during the time the emerging nymph is suspended just under the surface film that it
is most available to feeding trout. In fact the trout may eat the emergers exclusively and
pay no attention to the dun and spinners. Watch for rise forms to indicate trout feeding
on the emergers. Check the shorelines and slower moving sections of the river or
stream. The emerging duns won't be around for long.

Presentation:
Fish the Brown Drake emerger just below the surface to imitates the real nymph as it
moves from the bottom to the suspended location beneath the surface film. In the
slower moving water in which they are found, a downstream or down and across
approach may be best.
