There were at least two male Common Darters, Sympetrum striolatum, around the wildlife garden pond today. If you move slowly, they are great posers and allow very close approximation. Their faces are locked into a perpetual smiling grimace, adding to their charm. If you watch them from a close distance, you'll notice that they are constantly flicking their heads around, looking for insects flying overhead. If a suitable one is detected, they dart off, returning to their perch to eat their prey.
