Baetis Nymph? - Baetis tricaudatus - Female

Size: 8mm
I think this is a baetis nymph, and probably a female, due to the small eyes.

Baetis tricaudatus
Sandy,

I believe it to be Baetis tricaudatus.

Roger,

... I just saw the reposting of the photos and I agree with your assessment -- B. tricaudatus for the immature specimen (this one), but leave the more mature specimen at Baetis because the characters can't be seen. I'd be willing to bet that it's B. tricaudatus as well. ...
