The dragonflies are probably also trying to hunt down the latest butterfly!
It's not unusual for dragonflies (and damselflies) to be found quite a distance from water, particularly when they are still maturing. Moving away from water after emergence helps prevent the risk of damage through conflict or unwanted 'advances' - it also helps to allow the species to disperse and colonise new areas.
This one is a Large Pincertail (Onychogomphus uncatus
) - or 'Le Gomphe a pinces' if you prefer the French name.
