Moved from Mayflies.

from Lloyd Gonzales [received half an hour ago]:
"The only known Leptophlebia with dark clouds in the wing that would be found in the Pac. NW are L. nebulosa and L. pacifica. The dark area is usually confined to the apical third of the wing in nebulosa, and the irregular oblique dark cloud is usually attributed to pacifica. As far as I know, the known range of pacifica is probably restricted to a few counties around the Willamette Valley in Oregon. McDunnough's holotype of L. pacifica and Traver's holotype of L. vibox (a synonym) were both collected near Corvallis, OR in the early '30s. Dennis Lehmkuhl of the University of Saskatchewan might be interested in seeing Lynette's photo. He got his doctorate at Oregon State, and I believe he is very familiar with L. pacifica."

 
Great
Should I contact Dennis or have you already done it?

 
contacting Dennis
i haven't [i'm only aware of his work, but we aren't in touch] -- so i'd suggest contacting him directly

 
Thanks
I sent him an email.

 
From Dr. Lehmkuhl
I am glad to see that L. pacifica has a wide distribution. It should be safe and have a large population. I was under the impression years ago that it was known only from the Benton Co. area. Best wishes, Dennis

 
Leptophlebia pacifica
I have some information on L. pacifica on my website- dennislehmkuhl.com. See Oregon Winter Ponds on the side menu. Dennis

 
Thanks again,
I added it as a link to the info page too. You can see the info page here.

Leptophlebia
Lynnette-

This appears to be a Leptophlebia male imago, and probably L. pacifica, which I don't believe to have been previously reported from WA, although it is known from neighboring OR. If you have access to a library copy of The Biology Of Mayflies by Needham, Traver, and Hsu, a very detailed description of this male imago appears on page 539 under the name Blasturus pacificus, which L. pacifica was classified as in 1935, when this wonderful reference book was published.

 
Thanks
Roger.

gorgeous male imago
i'm anxious to hear from our experts
