ID this Mayfly

By the way, this is not a challenge like Taxon's. I just don't know what it is, but am curious, but also too lazy to try to key it out.

Hi Matt,

Your photos are of a Paraleptophlebia female subimago. I have cropped them below for easier viewing. Under what circumstances were they taken? Was it near the intake at the SE corner of the lake? The reason I ask these questions is that Paraleptophlebia are normally found in moving water, and not in still water.

Thanks Taxon! Yes, they were taken not far from where the spring gushes into the lake, so it's certainly possible that's where the nymph resided.
