It was still a young wasp when we got it (thirteen or fourteen years old) and for some time we could not get it to eat or drink, it was so shy. Since it was a female we decided to call it Miriam, but soon the children’s nickname for it-- " Pudge" --became a fixture, and "Pudge" it was from that time on.
