Newly emerged dragonfly?

Apologies for my delayed response, I have only just noticed this thread

The animal featured in the image is definately one of the larger Dragonfly species and a newly emerged or "Teneral" individual at that.

It is very difficult to make an accurate species ID from that angle unfortunately.  Habitat, locality and details of the situation would help.  The head of the exuvia (empty larval case) looks to be a Libellula.  The muddy substrate would then suggest L.depressa, the broad bodied chaser.  This species is widespread and common throughout southern England and Wales, and has expanded into the North of England in the last few years.  Emergence is usually well synchronised and occurs over a period of a few weeks from mid May. Emerging on a mud bank is not that usual however.  Such behaviour tends towards Orthetrum cancellatum, the Black tailed skimmer. This species is quite common in southern England, parts of Wales and central Ireland. Emergence occurs in early morning from late May to July.

It is often possible to get teneral animals to climb up on to your finger and then from there to climb onto some other vegetation if you need to get more detailed shots, dorsal views etc.  They do need to be kept vertical or else the wings can collapse sideways and that is the end of the individuals flying days. You can also collect the exuvia which can be identified to species.
