The late Larry Graham originated the Lightning Bug in
the early 90's on the Yakima river.
It has become what might be called a "Guide Fly": one
of the few flies that guides reach for when the
situation is difficult and they'd like their clients to
dangle a nymph and feel the rewarding tug of a trout.

The above taken from the book: "Nymphs for Streams and
Rivers by Dave Hughes. From Stackpole books.

1. Tie in the tails first and then tie in the
copper wire (brassie size) The yellow is
yellow paint that was on my thread. Since
this is a small fly, I used copper wire for the
underbody and extra weight.
2. Tie in a length of holograpic or pearl
tinsel at mid shank.
3. Wrap the tinsel to the rear and then back
to the tie in point.
4. Take four turns of tinsel for the rib.
5. Tie in a length of tinsel for the wingcase
and wrap a thorax of peacock herl.
6. Prepare a partridge feather by cutting
the tip leaving a v shape as shown. This gets
tied in at the front of the hook by the stem.
7. Finish the fly by pulling the wingcase
over the top and tie off.
