Not quite sure about my identification as I am not at all familiar with these lovely insects.
No interactions present.
Since I started visiting a wetland site regularly. I believe there are two "small red jobs" like this, and that the anti-humeral stripe (on the thorax, "north" of the wings) is a clear feature of this one.
I was rather surprised as this was resting on some geraniums in the garden but my location is rural wet fen boggy,well usually but this is the driest I have known were I live for over 17 years.I went for large as it was the one that was more common.
Yes, this is a female Large Red. There is a Small Red Damselfly - the male has red legs and eyes in addition to abdomen, and no (or hardly any) antehumeral stripes on the thorax, whilst the female has much more black on the abdomen - and you're well north of its current range.
It is the first time I have ever seen one here,I will keep an eye out for the male and thanks for the information as I know very little about these creatures.
