It was very useful to refresh my memory as to the differences between the Common Blue Damselfly (first two images with wine-glass abdominal markings and wide upper blue stripe on thorax, images 1 and 2), Azure Damselfly (Stirrup abdminal marking and blue and black stripes about even, image 3) and Variable Damselfly (Stirrup marking but blue stripe is very reduced and sometimes interrupted, also 'bat' marking on penultimate abdominal segment, image 4) during a survey at Paxton Pits yesterday. Other photos are Blue-tailed Damselfly, Emerald Damselfly (wings at 45 degrees), female and male Banded Demoiselles, Scarce Chaser and Emperoro Dragonfly.
