Three Stages of Growth in a Wasp Colony 



The front of a wasp's nest is seen at 

 the left. The nest has grown to an 

 empire, many broods having been 

 raised and each in turn having la- 

 bored to increase the colony. In 

 each of the cells the face of a young 

 wasp almost developed peers out 



Below are shown cells of the wasp's 

 nest, cut open to reveal the eggs as 

 deposited by the Queen. The cells 

 of a nest are not a) '.owed to remain 

 idle; as soon as cne wasp emerges, 

 the cell is cleaned out for another egg. 

 The young wasps are the workers

 feeding stage, and on the right a 

 wasp that is nearly ready to issue 

 into the world and take up the work

 grows to great proportions. At 

 length the old Queen dies, and the 

 young wasps fly away from the home
