Odonata (Anisoptera) - Dragonflies

Dragonflies are different from damselflies in a number of ways.  The fore wings differ from the hind, which are broader near the base and unlike damselflies, they are held out to the side when at rest.  The space between the eyes is always smaller than the diameter of the eye itself and unlike damselflies their nymphs do not possess accessory gills.

Four-Spotted Libellula - Libellula quadrimaculata

A common species around ponds and lakes, the name comes from four black spots (one at the front of each wing).  It is similar in size and shape to the broad-bodied libellula (below).

Broad-Bodied Libellula - Libellula depressa

A common species throughout Southern England and Wales. The Female is shown in the first four photos and the male in the next two.  The last four photos are of what I believe to be this species' exuvia.

Emperor Dragonfly - Anax imperator

One of our largest species, the emperor imago (adult) is on the wing June-July.  The first two photos show a female as she locates a suitable site and begins ovipositing (laying eggs).  The middle two were taken the morning after a storm, and it is likely that this teneral was injured as a result.  The final picture shows what I believe to be the exuvia of this species.

Golden-Ringed Dragonfly - Cordulegaster boltonii

 

Another of our largest species it is mostly associated with running water and can be seen from late June to early September.
