In most cases, queens will loose their wings soon after they have been impregnated during the nuptial flight. However, this is not always the case. Some queens may not loose their wings till the first workers ‘nantics‘ are born, and some may loose their wings and never lay any eggs. The best way to tell is to wait for the nantics to appear. Note: If a drone is the first adult ant to develop from the eggs, then the queen is unfertilized and not pregnant.
