Rover Ant Nuptial Flight
Brachymyrmex (Rover Ants) is a genus of mostly tramp species that have spread across the globe by human commerce. Colonies are more than happy to move into potted plants and are then transported around, usually a short distance but sometimes all over the place. It's not uncommon to bring a few colonies indoors in the winter time on accident either and species can be found in greenhouses throughout the world.
Flights happen in late afternoon along side Lasius claviger, but seem to favor muggy days with an over cast to them and a slight chill in the air. Around 70 degrees is ideal of course but this species seems to be cold hardy, like Prenolepis imparis. They tend to favor nesting spots in damp, sandy soil, and go unnoticed on account of their size. Any mound formed around the entrance is usually insignificant, and on par with what a Monomorium would make, lots of extremely tiny dirt partials, unlike what a Lasius or Dorymyrmex species would produce.
