Hammils Killer is a good NZ pattern that uses olive partridge feathers. A good damsel fly immitation. Basically, slim yellow or red wool body, black squirrel tail for the tail, then tie matched partridge feathers along the side "vertically" (should look like a little almond), usually one paired tied in mid-shank, and the others at the head. I can't find a photo of one right now, but here's a Lord's Killer (tied with Woodcock; just replace that with the olive partridge).
