Baetis notos

Hi Lynn-

I believe your mayfly nymph to be of of family Baetidae, genus Baetis, and strongly suspect it to be Baetis notus, based on the elevation where you found it, in combination with its distinctive abdominal markings.

Baetis notos

Thanks so much for the ID. We're excited about this mayfly larva. I remembered seeing a mayfly on the prairie. When I looked at the images, to my surprise I discovered we had taken photos of two different mayflies here where we live. We had no recollection!

Anyway, I am going to photoshop and submit one of them that seems to be a Baetidae with intercalary margins. Also, this one emerged in June. The different mayfly emerged in later April--far too soon for this tiny larva.

My post was confusing.

When this larva was First identified as a mayfly, I mentioned I had never seen the adult here in the foothills, only on the prairie. But later, when I looked at my photos, I discovered that many years ago we had photographed two different adult mayfly species here where I just found the larva.
One of the adult mayfly species was flying in late April. The other adult mayfly species was flying in June. This latter adult mayfly is the one I posted as # 1053598.

Mayfly larva

How fascinating! Our first mayfly here. There were s few of these larvae swimming around, so we'll be looking for the adult this year.

Thanks so much for your ID. It is much appreciated.
