Hello,

An opportunistic shot of a mayfly which landed on my car window. Unfortunately, no size reference. Can anybody narrow down the possibilities?

looks like a fem. Caenis to me

 
Thank you.
Thank you.

 
Caenis
Yes, Caenis, a female based on short tails, and a subimago based on the non-wettable hairs visible on the trailing edge of wings. Incidentally, this photo provides an unusually good view of the tail ends, which are often obscured by a white background, lack of focus, etc.

 
Thank you.
Thank you.
