This catchfly is a flower of the hour. Just got back from dropping the kids at the airport, on their way to taking a bite of the Big Apple. In the dark along the way I probably passed a bunch of these. I would only recently have recognized them. Night-flowering are remarkably similar to white catchflies or campions. Their difference is evident at the mouths of these flowers. Night-flowering has stamens and pistils on separate flowers, while white campions have them all in one. Here, the flower on the left is staminate. And yes, this picture is posed, since they were found on two different plants. The flowers will remain open into the morning.
