Help identifying this insect in Connecticut?

Question

This is what I can tell you about it: Looks like an ant with a black body, except it has long thin legs like a spider that are a lighter brown, and it flies. It will sit on the ceiling or on the window screens, but I have never seen them on the floor. They aren't attracted to light. I always see them mating and they keep reproducing on my porch. Help identifying?
