Golden Ringed Dragonfly

I took these pictures a week last Sunday in Harwood Dale.  Having just started to walk from the barrier onto the forest track we soon came across certainly 3 maybe 4 of these dragonflies and this one set down for a good while.

The pictures were taken at the long end of my Sigma 50 - 500mm lens, and to be honest I am a tad disappointed certainly with the side views. From behind with the sun light over my shoulder the results are nicer.

I took pictures of this dragonfly a few years ago and perhaps the results using my prime 400mm lens, which supposedly is also macro were better.

These are certainly easily recognisable dragonflys being big (70 - 100mm), the black and yellow body pattern, the eyes just meeting in a point on the head. Apparently the male has an anal triangle at the base of the hindwing and auricles on section 2 but even zooming right in I cannot tell! Perhaps someone can help.

I would ask you to double click these pictures to look at them in a larger size.
