ID comment

The black mushroom mark on abdominal segment 2 of the blue male is unique to this species of damselfly.

"Mushroom" mark.

As a 'typical' marking the mushroom mark on S2 of the male is unique to Common Blue Damselfly, but some individuals of other species can show almost identical markings (Northern Damselfly and Dainty Damselfly for example).
The wide antehumeral stripes (the blue stripes on top of the thorax), and other features, also help to confirm the ID.

Location is also another factor to consider.

Sure is!

Yes, location is always something which should be considered, and it is always most likely that an individual (of any taxa) will turn out to be something which is known to occur in the area.
