All you need is some 2mm craft foam and some peacock quills. Use the foam to create the shellback and head and the peacock herl for the underbelly and legs... use some super glue in the process to hold things firmly in place and add a small thin piece of brightly colored foam for an indicator and your good to go.
A simple fly to tie and super effective. I fish these flys a lot both here in NY and in MT with great results. When there's nothing hatching, try a beetle they are available to the trout throughout the summer so the fish see a lot of them. Funny, most fisherman seem to neglect using them. I've had more than one client turn their nose up when I've suggested tying on a beetle, that is until the fish rises and takes it.
