Photo taken in Elkton, Oregon - September 03, 2010. I believe it's a White Miller, and was wondering if it could be ID'ed to species.

I also believe it to be family Leptoceridae, genus Nectopsyche (White Miller). However, species identification would likely require it being physically examined under a microscope by an expert like Dave Ruiter. To my knowledge, there are records of only two species in OR, but it is always possible for it to be a species which has not previously been recorded for OR. How am I doing, Dave :-)

Regarding your question of whether the darker gray on the apical 4th or so of the wing is natural, my belief is that what you are seeing is shorter hind wings being overlapped by longer fore wings, and that this becomes more obvious under certain lighting conditions.

Roger - you are now "king of the lab" Except the "expert like Dave Ruiter" stuff. He gave up on Nectopsyche adults along time ago - there are a couple species he can easily distinguish with a scope but otherwise he cannot tell them apart. even with a scope.

Yeah right, Dave. The real expert "doth protest too much, methinks."
