Deon,

I like these as my emerger patterns for BWO.

I tie then in sizes 14 - 20. Both are pretty simple ties. Top fly is Olive Pheasant tail, Snowshoe Hare for the post, Bronze Dun Hackle and a bit of olive dubbing. Second fly is a Klinkhamer. olive dubbing, peacock herl, dark dun z-lon or antron for the post and Bronze Dun Hackle.

THis might give you a couple of more choices to add. Your flies look great by the way. My guess is the fish will be the final judge but they are well executed and look buggy enough to catch fish.

Is a blue dun the same as a BWO?

My understanding was that a Blue Dun was another nickname for a Quill Gordon - a hatch that, to the best of my knowledge, doesn’t exist in Wisconsin.

Here’s my best guess as to what this is - if it’s not, it’s gonna work anyways.

Hook: Dry Fly 16-22 (the earlier in the season, the larger the hook)
Thread: Olive
Tail/Shuck: Natural Partridge fibers
Body: Olive Dubbing
Wing: Medium Dun CDC tied in EHC wing style. Try to get a “full” wing. You’ll need to use more than feather; try 3 or 4 stacked on top of each other.
Head: Some more olive dubbing

If you don’t have CDC, dun hair from the foot of a snoeshoe rabbit will work as well.

New thought:

Troutnut.com has Blue Dun listed as a common name for the Blue Quill aka Paraleptophlebia adoptiva. Apparently, these are present in Northern Wisconsin.

So, the hook would be about 16-18
Trailing shuck of natural hungarian partridge (darker is probably better)
Body and Head: Mahogany dubbing (another common name is the Mahogany Dun)
Wing: Pale CDC

Here is my favorite Blue Dun emerger pattern…Vary dubbing and wing to match the particular hatch.

The LTD (Long Transitional Dun) was born as the result of a chess match with a Sulfur hatch on the West Branch of Pine Creek, in Central PA. It is hands down my most productive surface pattern, and has proven it’s worth coast-to-coast since. It also ties well as a BWO, Light Cahill & Slate Drake.

Hook: Standard Dry #16
Thread: Olive 8/0 Uni-thread
Thorax: Yellow/olive Hareline Dubbing
Tail: Pheasant Tail
Abdomen: Pheasant Tail (in thread loop)
Wing: Light Dun CDC
Hackle: Medium Dun

I stand corrected. I miss read Blue Dun as Blue Winged Olive, my bad. If the information I posted isn’t relevant please ignore.

Yep, the blue dun patterns are meant to imitate the Paralepdophlebia Adaptiva (sp?) hatch. Blue Quill. In larger sizes they make a descent Isonychia.

NO, my fault, I misread “blue dun” and listed some “bwo” pattern links.

The reason I asked, talked to a guy on the river in the midst of the caddis hatch in Colorado, and he wasy fishing a blue dun, and catching all kinds of fish. Said that was his go to fly, but I don’t know that there are Blue Quill in Colorado, that seems like an Eastern bug. Anybody know about this?

The Blue dun is a common name for the Blue Quill. However, with the variations in coloration from one hatch or stream to the next, one streams blue quill, can be the same color and size of another streams pale evening dun, pale morning dun, Blue-winged olive…etc. So a common “blue dun” pattern can often work on multiple hatches as long as it matches close enough in shade and size. It’s even further confused when it comes to using actual hatch names, and naming a hatch after the pattern most commonly used to fish it. Example, the “Light Cahill” hatch:^)

In his book, AK’s Fly Box, AK Best lumps Quill Gordons, Hendricksons and various flies called Red Quills together. I think the Western Red Quill is T. Hecuba (the name may very well have been changed).
