Along with a plethora of Migrant Hawkers one or two darters were flying too.
No interactions present.
At this time of year almost all darters will be Common (even the ones with no yellow on the thorax and apparently all black legs).
The flying one in this post is definitely Common (well marked yellow stripes on the sides of the thorax). The perched one is more difficult to be certain of, but a male Ruddy would be expected to be far deeper red, with a more pronounced 'waisted' abdomen (I would not expect yellow stries on the legs to be visible in this shot).
I allowed my heart to rule, I was fairly confident you would overturn me so I’m not that surprised. Just nice to see so many flying still, keep up this weather I say.
