I have had a whole squadron of common darters hunting in the garden for the last few days. They ate clearly finding prey above the long grass. It is noticeable that they are hunting here and not next door, where the grass is kept significantly shorter. Darters don't come and hover in front of you, checking you out in the way that hawkers do so watching them never feels quite so interactive in that sense, but then, they will occasionally come and perch on you instead. Either way, I am very happy that they are around.
I've noticed them in my garden too, over the last couple of weeks!
