Attracted to porch light. I assume it walked there as it's flightless.
No interactions present.
Probably did walk, they climb up things, but I have seen some insects flying 'in cop' with one of the pair doing all the flapping. It might be possible that this was carried in flight by a male, although I've never seen this behaviour in Winter Moth and they seem quite weak flyers anyway.
