Jan you take beautiful photos of these dragonflies (and other subjects)
I'm curious what marks a male cf a female?
I saw the end of the "tail" had a bit hanging below it in one but I think you said that was female.
Only thing I could see that was different apart from some colourations
R5 , 600mm. F4 L IS II , RF 100-500, EF 100 F2.8 L IS macro, 1.4 Tc.III . 

On the brighter side, I got a few pics of a blue damselfly.
