Cryptic Wood White - still on the wing? (1 Viewer)

I'm in Belfast for the day on Thursday and weather permitting I'd like to see CWW if possible. I appreciate it's getting late and I've missed the peak, but does anyone know if they are still flying and if so any locations with directions in Belfast City please? I have been told of Harbour Meadows and Lagan Meadows but don't want to just wander round aimlessly if I can avoid that. Many thanks for any help in advance.

Answering my own question, yes. Saw one quite fresh looking CWW at Belfast Harbour this afternoon.
