its called the nuptial flight, and i'd bet not many of us know these insects are the very same underground wood eating, castle building swarms nature has blessed us with. we most of the time hate the nuisance they bring after a heavy down pour. The broken wings which later becomes thrush and difficult to sweep away. They sneak in through the trap doors just to find a source of light in a fizzling display around sodium and fluorescent lamps at night when there is a rain. the tandem running and chasing usually lasts until a female attracts a female by emitting a pheromone to attract the passing males. after a couple have found each other, t hey do the tandem chase until t hey find a safe spot to start a new termite colony. these two pair will later become the Queen and king in the colony.
