Not just sort of white, snow white. I couldn't catch any for pics as they dipped and rose from the surface. Not huge,not small,just a fairly abundant medium sized mayfly. Any thoughts?

There were a few females dipping again and without a net I didn't stand a chance. Being the first of June I have to think Green Drake. The less than monsterous porportions may just be a local thing.
