Here's one that has been very effective on bluegill for me this summer. It's grouse for the hackle and pheasant tail wrapped around the hook for a body.

I long ago lost count of the number of bluegill that have been brought to hand on this fly.

It's really easy to tie which is a good thing. After 15-20 fish, it's pretty well battered and bruised and it's time to tie on a new one.
