Stream Mayfly - Stenacron interpunctatum - female

Stream Mayfly - Stenacron interpunctatum - Female
Kokomo, Howard County, Indiana, USA

Is this a female?

Moved from Stenacron.
Thanks, Mack!

This perfectly aligns with (Stenacron interpunctatum / canadense). It most likely came from a pale substrate thats why the sublateral abdominal shading is missing. True to form canadense does not have spiracular spots but is darker like this one.


female imago, yes
