Variations

These crustaceans match the overall coloration of their environment.  If the water they swim in is clear, they will exhibit a pale gray coloration; if the water is has an olive brown cast to it, the bug will show that coloration.  Trout can be caught on pink scuds, which imitate dead scuds.  The most common colors are gray, grayish olive, olive brown and pink in sizes 12 to 18.



Fishing Techniques

When moving through water, scuds move very slowly.  Use a dead-drift presentation in a stream; a bit faster in lakes, such as a slow hand-twist retrieve.  This fly is quick and easy to tie so don't hesitate to work it around sunken brush surrounding your favorite trout lake.  The scud is best fished using a shot and indicator or fished as the dropper on a two fly rig.
