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.
