Also, thanks for your excellent hummingbird hawk moth pic. We had one in the garden at the weekend (first sighting) and I would have had no clue what I was looking at if not for your post. You were right about them being hard to capture - I got nothing. :-D
Nice photos. I think the last one is a Southern Hawker (female) - see https://british-dragonflies.org.uk/species/southern-hawker/ for some examples
