Hi all,
Lovely photos, I can add a few I.D's. The large green Dragonfly is a female Emperor (Anax imperator) she is laying her eggs. The other brown Dragonfly is a Brown Hawker Aeshna grandis. The Damselfly is a male, he is probably the Common Blue Damsel Enallagma cyathigerum, as he only looks to have 1 thoracic stripe. The Azure Damselfly is also very common, and looks very similar. The Bumblebee is feeding on the Globe Thistle (Echinops ritro), she is a worker of either Bombus terrestris or B. lucorum, probably the former (the yellow stripes are bright yellow in B. terrestris and a bit paler in B. lucorum), but they are difficult to tell apart. Interestingly although we don't have many species of Bumblebee putting a definitive name to many of them (or almost any bee or wasp) is quite difficult.
The white butterfly is a Large White (Pieris brassicae), 2 obvious black spots and a large black wing tip mean that it is a Large White and not a Small White (P. rapi). Green-veined White (P. napi) is the other common one, but it has green markings on the underwings. The flower it is feeding on is Verbena bonarensis.
