A wasp of the genus Polistes, the most common type of paper wasp, on a vespiary. There are over 300 recognized species and subspecies, making it the largest genus within the family Vespidae. They commonly build nests on human habitation, where they can be very unwelcome, although they are generally non-aggressive.Photo credit: Muhammad Mahdi Karim
