I had a couple of ideas which I might try to tie when i get back home.
The first was a foam suspending buzzer tied on a scud hook, with peacock herl abdomen, gold wire rib, a dark (brown?) foam "bubble", and white ice dub tied over the bubble.
The other was something I have tried to tie several times with limited success a caddis dry with peacock body, dubbing for an under wing, foam cut into the shape of a single wing then split most of the way through to create a wing case, hackle to match casing.
