Hi all!

Collected from broken branches in Sussex, Southern UK

What am I looking at?

Chymomyza caudatula males for the bottom two on the left? (on the UK list since 2019?)

What is top left and the two on the right? fuscimana? distincta? Something else?

Can I possibly tell without killing the fly? What character would I need to photograph?
