TIIK FKONT OF A WASP'S NEST 



The cells of the nest are not allowed to remain idle: as soon as one wasp emerges, the cell is 

 cleaned out and another f^g laul in it. Later in the fall the cjueen's sui)ply of fertilized eggs 

 is exhausted, and she then lays eggs which have never been fertilized. They contain no 

 inheritance from a male parent, hut represent only a mother. These unfertilized eggs 

 develop into males who, after fertilizing the females, quickly perish. The neuters like- 

 wise perish at the beginning of cold weather, and the only members of the colony who 

 survive are the fertilized females, who are ready in the spring to start nests of their own.
