Sure AK. (Nice job on the caddis larva BTW).

Tiemco 100 or other dry fly hook/thread to match the body color. The tail and back half of the abdomen are maribou, lt. tan or grey ususally but you can vary the colors to match your local mayflies. Tie in the tail then wrap the butts halfway up the hook. Ahead of that is a ball of dubbing, rabbit or synthetic. Then mount the deer hair wing pointing forward and clip the butts above the dubbing ball. Tie in and wrap hackle color of your choice on top of the wraps holding the wing down. Pull the wing up and out of the way so you can finish the head and you're done.

Have also tied it with a pheasant tail back end and caught fish on it.

Only apply floatant to the front half of the fly so the back half can hang in the film like an empty shuck. It imitates a mayfly that is having a problem fully emerging, an easy target for the fish.

If you are coming back down this way next summer it would be a good fly to bring along!
