Yellow and Black Popper mixed with my Tiger Popper

I tied up a bunch of these guys tonight in size 8.  I dont know what it is but the smallies love the yellow and black guy.  I have often wondered if it is due to the color combo matching a bee but I am not sure.  Whatever it is, they love it and I will keep making it.  I call the other guy my Tiger popper based upon the color combo and not because it has stripes.  It also produces.  I LOVE TOP WATER FLY FISHING!  I cant wait for Summer time!
