Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Figured since there was a fair amount of discussion about Baetis nymphs lately I'd post these photos. They're all of the same species.
I've been able to key these nymphs to Baetis but have no idea which species they are. Any suggestions welcomed.
All were taken out of the Russian River. The nymphs range from 5.5-6.5 mm in length (excluding cerci). The date each photo was taken is under the photo. All specimens were alive when the photos were taken.
