A few weeks ago whilst fishing a comp with Gadusamora and Sunray a number of mayfly were seen by us all coming out of Savages, I kind of forgot about it but then yesterday I saw them again trickling off between The Seat and Gaynes Cove.
I have never heard of mayfly on Grafham but this is definitely not a case of mistaken identity as I know what a Mayfly looks like

and as I say I wasn't the only one to see them.
I haven't seen any rise to them, but the gulls were picking yesterday, I stopped fishing and parked in the middle of the hatch and gulls were picking for them as they emerged around me, normally the boat pushes the gulls away but these seed to like what they were eating enough to ignore me.
Just wondered if anyone knew if they have always been present or if it's a new thing?
