These fabulous photos of Ruddy Darter have been sent in by Jim Almond. Taken at Venus Pool they show a male with a clearly waisted abdomen, black legs (no yellow stripe as seen in Common Darter), a ruddy frons (face area) and a diagnostic black T shape on top of the thorax.
Further a field Stephen Barlow has photographed what are presumably the last few White-faced Darters for this year at Whixall Moss (far below left and right). This is definitely a Spring species which dwindles at this time of year just as Common, Ruddy and Black Darter really take to the skies.
