Insect procreation (second in the series)

I went fishing at Butterston Loch yesterday (near Dunkeld). Didn't get any good pictures of the osprey unfortunately. However, I did manage to catch something on a difficult day when the only bug-life seemed to be dragon flies. I also got a blip of these dragon flies, I'm not exactly sure what they're doing but I don't think they're just playing at boats.
