Pseudiron centralis
Hi rsdem-

I believe this mayfly nymph to be Pseudiron centralis.

Please either update the date this image was taken, or respond to my request with the date the image was taken, so I can update it for you.

Moved to Ephemeroptera for expert attention
Moved from ID Request.

Roger, our mayfly expert, will take the ID further.
