Winged Termites

I believe you have photographed winged termites. They can be somewhat difficult to tell apart from winged ants, but ants will have elbowed antennae and a thin waist. Termites have two pairs of wings of the same length while ants have smaller hindwings. You may remember something that I can't see in these photographs or you may be able to zoom in on the original photos and see more details. I'm guessing but I think these are termites.
