Bob Kemp has sent in this great photo of a Four-spotted Chaser and wonderful reflection! It is a form called praenubila which simply has more black at the wing nodes and towards the end of the wings, but the overall effect makes it look rather like something more exotic! Below left is a close up of a female Four-spotted Chaser ovipositing and bottom right a male White-faced Darter on the wing in some extraordinarily hot conditions at Whixall.
