Here's another such pattern. Entire silhouette and idea is similar to good old Compara Dun but there are subtle yet distinctive modifications. I do prefer either turkey- or goose-biot abdomen to dubbed one. Then wing is composed of partridge and CDC feathers. These are much slimmer and quieter than deer-hair on Compara Dun yet very visible and high-floating (treated correctly).
Here's a PMD. Size 16 & 18.
I put some emphasis and variations on Baetis = Blue-Winged-Olive. Size 18, 20, 22, & 24.
First, here's a dark-olive. This would be perhaps most of anglers think of baetis, and it works most of times.
Followings are color variations but each one can be very important for a certain situation.
Especially during the fall baetis hatch at Livingston's spring creeks and at some Yellowstone Park waters (Lamar, Soda Butte, Slough, Firehole, Madison), we often encounter "baetis" in several different colors. Old-timers still use "pseudo" in that matter.......... You'd better be prepared.Gray.
Here are just a few proof pics!!
Specify colors & sizes.
PMD - 16 & 18
Baetis - 18, 20, 22, & 24 - dark olive, gray, dark gray-olive, or light gray-olive
