Dragonfly, Chipmunk And Bee

I went to North Weald for the Vintage & Classic Fly-In. It was rather disappointing as the only classic plane there for a time was a Tiger Moth. Plenty of local modernish light planes arrived but the poor vis and threat of thunderstorms put owners of classics from further afield off. I was just leaving when a Dragonfly and a Chipmunk arrived. (Extras) I shot a Spitfire going in the direction of North Weald when I got home.

Lots of bugs about this evening. Loads of mating robber flies, which I blipped yesterday. Every pair was carrying prey. I'm wondering if this is part of their courtship behaviour?

The solitary bee in my pic was sitting on and ox-eye daisy and didn't want to budge.
