From the color you could be right. But the abdomen looks too round in profile. It should be flattened for a skimmer.I guessed this was a female Blacktailed Skimmer ...
You are probably right. The two females are quite similar but it does look like a young darter flirting with the skimmers.
Looks like it has had some adventures...I have never got this close to an Emperor Dragonfly before, it was just a few cm beyond the 3m mfd of the lens.
What shutter speed are you using to freeze wing motion?Feeling a second class citizen because I haven't an R5, went to a lake with the old DSLR to see if I can still do BIF. My cameras all have a flaw that makes BIF difficult - no flying birds. Instead, got a DIF of an Emperor coming straight at me. It was 10m away.
