Hatches Made Easy:

Blue-winged Olives - Our "Perfect Fly" Pattern Colors
January (1/14/08):

About the biggest mistake you can make fishing the blue-winged olive hatches,
is to
use too large of a fly. This is easy to do considering that most fly shops
stock and sell much larger fly sizes. They know that anglers don't really like small
flies and they think they can sell more of the larger ones. They are right but the
angler is wrong to buy or use them. Blue-winged olives are small mayflies. The
species in the park range in size from a hook size 18 to 22, mostly size 20 and
22.
The other big
mistake that is common, is to use heavy hackled flies. Many fly
tyers teach tying heavy hackle flies for the rough water in the Smokies. These
mayflies are tiny, slim mayflies. Heavy hackled flies don't match them. If you
need heavy hackle to keep your dry BWOs floating, that means only one thing.
You are presenting them in the
wrong type of water.

some depending on the particular stream,

baetis and brood. They should
be very close to these colors but if you find
the naturals are a different color, you may
want to change to match them more
accurately.
