Stage, not species
It took me a while to figure out what had happened here, Lynette. I think my word order in the previous post may have been confusing. This is a male imago (the final adult stage of mayfly development, also known as a spinner) of the genus Paraleptophlebia. Both of your Western specimens should be included with the others of this genus on the Paraleptophlebia page.

The other clarification is that "Jenny Spinner" is the nickname applied by old-time fly fishers to any male spinner (imago) that displays a dark thorax and tip of the abdomen with the rest of the abdomen translucent and whitish. Although some (but not all) Paraleptophlebia species show this pattern in the male imago, the same pattern is also found in the male imago of species in other genera (such as some Maccaffertium in the Heptageniidae and several species of a few genera in the Baetidae). Many fly-fishing "common names" are more descriptive of color than genus/species, hence the constant taxonomic confusion that results from the use of common names among anglers. For example, fly fishers have applied the nickname "Blue-Winged Olive" to forty (or more) mayfly species in several very different genera.

 
:) Thanks
Sometimes I can be way too literal and add that to I don't know squat about mayflies.... :) Thanks for the clarification.

Moved
thanks Lloyd.

Jenny Spinner
I believe this is a male Paraleptophlebia imago. The hindwing (though a bit difficult to see clearly) appears to be oval without pronounced costal angulation. Paraleptophlebia has three tails of relatively equal length (compared to the thinner, shorter middle filament of Leptophlebia), and the males of many species in this genus display the "jenny spinner" coloration--dark thorax and tip of the abdomen with the rest of the abdomen translucent white.
