In a bizarre turn of events during the third T20I between South Africa and India in Centurion, the play was stopped for an unusual reason. Not due to rain, a break in the play came due to flying ants who wreaked havoc by coming in numbers.
These flying ants are common in that part of the world and usually come after a few days of rain, and there was some rain a few days before the play. So, when the weather becomes slightly warm and humid, they come in the late phase of spring.
