Mayfly - Siphlonurus occidentalis

Mayfly - Siphlonurus occidentalis
Bull of the Woods Rd., Northside at Taos Ski Valley, Taos County, New Mexico, USA
July 11, 2011
Size: ~10 mm body length
On my hand. These were swarming where a little water was draining across the trail. They often held their bodies nearly vertical and flew up and down a foot or two.

I'll move these to Mayfly sometime tomorrow if nobody IDs them more closely.

I don't know whether any of the rest of the pictures are useful—they show things that aren't visible here, but they might be frass. On the other hand, I could upload pictures that show things cropped out of these.

Male because of the eye shape, right?

Thanks
to =v= and Roger.

nice series; looks like a male imago Siphlonurus to me
for the future: to have your images noticed by the experts and get IDs faster, post all caddis-, stone-, and mayfly pix to the respective order pages rather than to ID Request; pls refer to this forum thread for more recommendations to help expedite the process
