Mayfly - Acerpenna pygmaea - Female
Columbia, Boone County, Missouri, USA
September 5, 2021
Size: 5mm TL body only
Very small - measured body only length of 5mm. Looks similar to some Isonychia I have, but doesn't completely match and this one is pretty small. Any IDea what this is? Thank you!

Hi Jon-

I believe this female imago to be Acerpenna pygmaea.

Thanks Roger!
That's really neat that you could IDentify this one. Adds Missouri to its Data.
