Male Ephemerella subvaria (Hendrickson) Mayfly Dun Pictures

 I collected this male Hendrickson dun and a female in the pool on the Beaverkill where the popular Hendrickson pattern was first created. He is descended from mayfly royalty.

This mayfly was collected from the Beaverkill River on April 19th, 2006 and added to Troutnut.com on April 22nd, 2006.

Look at the ruler. There are 10 clicks to a number.
I believe that we are looking at millimeters, not inches,
IMHO.

Jason:

Looking at the fifth photo from the top (the one with the ruler under the fly), it would appear that if you were to rotate the fly just a bit to the left, it would show that the fly is over one inch (25mm) long. That would make it twice as long as any Hendrickson I have ever seen. The average Hendrickson (to the best of my knowledge) is usually around 10-12mm (or about 1/2 inch), hook size 10-12. The hook size just doesn't seem to fit either. Where am I going wrong when looking at this fly (and hook)?
