Outstanding work, lx-88. Incidentally, in case anyone is interested, its body length was 25 mm, both as a subimago (dun) and as an imago (spinner).

Hi there, OMJ-

Nice to hear from you again. As you probably realize, fishable Hex hatches are largely limited to one particular lake here in WA, and they mostly come off after dark. Don't know about you, but I don't particularly enjoy fishing after dark. Some do, but it's just not my cup of tea.

In answer to your (likely largely rhetorical) questions, no bug looks like a Royal Wulff. Having said that, it has long been one if my favorite searching patterns for skinny water. And, a Soft Hackle does an effective job of imitating a caddisfly pupa, particularly on the upswing.
