Fly of the Month
The northeast corner of Yellowstone Park has abundance of light colored mayflies
that hatch throughout the summer and early autumn. In order to cover these various
hatches with just one pattern the tyers at Blue Ribbon Flies developed the SLS. Although
it was originated for the Slough, Lamar, Soda Butte drainage (hence SLS) it can be
used anywhere for smaller light colored flies.
When tying, start with the wing tied Comparadun style. Lay the zelon over the back
of the wing and bind it to the hook shank with the tying thread down to the tail
position forming a slim abdomen. Trim the zelon to form a trailing shuck. Stand up
the wing and figure eight a thorax with the dubbing. You Tube has a video of Craig
Mathews tying the fly. All materials may be obtained from Blue Ribbon Flies at www.blue-ribbon-flies.com
