Not sure about flies but I've noticed a big increase of midges/mossies when fishing in the evening. They seem more aggressive, refuse to go away, a real nuisance, sucking the blood and life out of me, getting me down and stopping me fishing.........just like living with the ex wife!
Those tiny little gnats/midges whatever you call them are there in their thousands on the weir. They like the bit underneath the peak on my baseball cap. I've found it distracting when trying to watch a quiver tip.
Anyone else noticed an unusual increase in the amount of flies this year?
I've seen in at home and also when we were in Wales a few weeks back. There seems to be a large number of particularly stupid and awkward ones that seem incapable of finding an open doorway through which to exit. Bizarre. You'd almost think there was a rotting corpse in the garden of something...
