I need to change my pattern (I don't have the right black feathers). I wound up doing a larger version of a Mercury Midge, using Spanflex for the body. I tried it out at the stream by the house and caught 4 bluegills, and 3 Rainbow trout (they didn't seem to mind that it is huge, for a midge...) in less than 45 minutes.
Since it uses a different body material, I guess I'll call it the Giant Mercury Bluegill Bug.
Hook: sz. 14 scud
Thread: 6/0 black Unithread

They'll go out in tomorrows mail.
