I was surprised to see a Comma butterfly in the garden a few days ago, it being late October, poorly photographed with an outstretched arm to where it was on the top of a 2m hedge. However a bit of research shows that I shouldn't have been so surprised as butterflies are to be seen in the UK from March to November. I also wonder if that bracket is gradually widening further with the warming climate. So there may be butterflies for a month yet, perhaps especially with the very mild weather we've had recently.
