This butterfly has been hanging about in my garden for the last two days:
Butterfly 1 Buterfly 2

It is still alive, and it moves around a bit, but I think it is having trouble straightening its wings. It can flutter a bit but doesn’t seem able to fly more than a foot or so.

Should I leave it and hope it will get better, or put it out of its misery? I don’t want to splat it unnecessarily but it makes me sad to think of the poor thing out there in pain and distress.
