Reminds me of another old pattern called the Mosquito. It's tied with the same light and dark moose mane body; either grizzly or adams hackle and tail; and girizzly hackle tip wings, sometimes upright and sometimes down. Not my fly or photo, but here's a good example ...

I've also seen light and dark moose mane used for midge larva and pupa bodies.

It does make a very nice segmented body.
