[QUOTE="SteveClifton, post: 1274937, member: 48420"] Steve, While I'm happy to accept I got this one wrong, I wonder if you could comment more on how reliable these features are for clinching this as a Ruddy (specifically the dark sides to the abdomen). I attach a shot of a darter that I identified as Ruddy last year, based on the following features: Black legs with no pale stripes. Pinched-in waste and relatively short body (compared to Robs photos) Black line extending down the side of the frons. Small amount of saffron yellow on the bases of the wings However, note that it doesn't show completely dark sides to the thorax. In Robs pictures it's difficult to see reliably whether there are any paler markings on the thorax sides because its wings obscure this part of its body. Nor can its legs be seen well enough to rule out if there are any stripes. As I said if I'm wrong then I'm wrong, but you seem to have over simplified the case for this being a Ruddy. Clearly these two are a tricky pair if not seen really well. Comments welcome.... Steve [/QUOTE]
