Perdigon Fly

[McFlyLures 0]

The Perdigon came from competition fly fisherman who started the "euro nymphing" technique.  They would fish a heavy fly, preferably on a jig hook so it would not snag the bottom.  Generally they lift the rod to keep the fly a certain distance off the bottom.  The tournaments would not allow split shot or indicators, so they adapted to make a technique where they could still catch fish without using them.  The Spanish most likely came up with the pattern, however I believe the French popularized it.  Kinda like the Frenchi fly, this is fished for the same reasons.  The smooth and thin bodies help sink even quicker than some other euro nymphing patterns (like the frenchi) and also being fully coated in resin make these very durable.  

The best thing about these flies is the versatility.  You really can make just about any pattern you want with these.  Choose different color threads, use different tails, and different ribbing materials as well.  I mean you really could make just about any bug imitation you want.   Caddis Larvae, midge pupa, mayfly or baetis nymphs, etc.  They really are very versatile.  Just change up the size, colors, and you have a different bug immolation.  They are also very quick and easy to tie.  So you can fill a box quick with very effective nymphs.
