First Mayfly of the year.

After the weather we have had I have struggled to believe that I saw my first Mayfly (Ephemeroptera) of the season today. I usually see these on my local river at the end of May so to see one this early makes me ponder..........why this early?

As you do, you take your cap off and grab the opportunity to snatch a look at this great insect.

Here is the culprit on my rod cork.
