Ephemeroptera sp - Stenacron

Ephemeroptera sp - Stenacron
Salaberry-de-Valleyfield, Quebec, Canada
August 24, 2013

She is not uncommon
Its her black, or shall we say!! lack of black markings that are untypical.

Stenacron 4 sure
This is a very interesting one for sure. It appears to be a under maculated sample mean it lacks black markings in certain areas or they are incomplete. This one is more of an untypical sample. However based on what can be seen I would call this sample a
(Stenacron interpunctatum / majus).


Stenacron interpunctatum / majus
I understand from your comment that this is an untypical ephemeroptera. A real luck for me to have photographed this insect.

Thanks for the ID
