(LOL) Funny you should mention this, my buddy just asked me that same question two days ago. The answer is yes! Before I give you the pattern the answer to the next question of " Do they work? " is also yes. Very simple pattern and people might frwon on this but all that matters is is it works. Here you go.
Hook: 3x - 4x long sizes 8 -14
Thread: rusty brown or orange 6/0
Body: a tan rubber band!
Legs: two turns of a brown hackle clipped short
Head: thread.
Also, to give it a little more realism I use a orange marker an the back to darken it a little, and I'll sometimes bend the hook slightly up(bend eye away from the bend a little) wich gives it an apperance of moving in the water.
I tried these patterns last spring during our trout season and caught a lot of trout and a lot of panfish on them. Hope they work for you as well if you try them. Good luck,Dave
