Ok I would call this a green drake, although it is also referred to as
a coffin fly, i believe??

Ephemera guttulata I believe at the time in the spring I only had hatch's to compare to so could be wrong.

Notice that the date is May the 5th and the size is 19mm on the score
board. I started photographing all insect with a likely name and size
because I was taking between 50-400 photos a day. I was new to my camera
so many were so so but next year they will be better.

The reason why the date to me was important. Notice the very full development in the wing pads. Typically here in southern Ontario the green
drakes are not hatching till last week of May. The water temp was
41 degrees that day and I was concerned we may have premature hatching,
and we did. The drake were popping out by the tenth of may.

Because they were in the same file I included pic's of one of my female green drake spinners imitations.

Lest we be accused of ignoring this one too, you are right Mack. :) Ephemera guttulata (Green Drake) can be distinguished from the other species in this genus by the solid colored dark terga and the lack of pared horizontal markings on the sterna. Some older papers reference a difference in the frontal process but McCafferty '75 mentions this character as unreliable. They are generally a little stockier as well, though this is harder to discern in isolation.

BTW - cool flies!

I added to many picture posts at one time :) So we can all agree
that this one is E guttulata or the famous green drake.
