With all this sunny weather and given that we are in the middle (or maybe the end) of the maylfy season I had to get on the water this week. Boy am I glad I did! Those wild brownies threw caution to the wind and engulfed my mayfly nymph and adult patterns with conviction.
Does anyone know what the typical dates are over which the big Danica mayflies hatch in Southern England? I thought late May to mid June but they seem to still be coming off. Maybe, like so many things in nature, the mayflies don't follow the Roman/human calendar and track instead to the rythms of the seasons: so if the summer is "late" in terms of our human calendar the mays might emerge later into the summer, but on their calendar they are hatching consistently on water temperature or some other indicator of where they are in the progression of the seasons... make sense?
I'll go out tomorow and see if they are still hatching...

i am sure the insects don't care about the roman calendar! we will see more and more odd insect behaviour based on changing weather patterns and climate
