Bloated, pendulous abs

Observation - Bloated, pendulous abs - Southern Africa. Description: I rescued this wasp drowning in the dogs' waterbowl and set her in on a sunny leaf to dry out. About 20mm body length. Abdomen huge and 'floppy'. Possibly water-logged from the near drowning? Or a queen ant?
