PROBLEM IV. WHAT DO WE MEAN BY COMMUNAL LIFE 

 AND DIVISION OF LABOR? 



Individual Projects. Give a report on the life habits of a solitary wasp. 

 Work out with diagrams the life history of some communal insect. 

 Keep a hive of bees and report to the class on their habits. 

 Make an ants' nest and keep a colony of ants in it. 



Solitary wasps. Some bees and wasps lead a solitary existence, 

 the digger wasps being an example. Each female wasp burrows 

 in the ground or in 

 wood and constructs 

 a nest in which she 

 lays her eggs. The 

 nest is provisioned 

 with spiders and in- 

 sects which are not 

 killed but are stung 

 into insensibility. 

 The nest is closed up 

 after food is sup- 

 plied. When the 

 young hatches it 

 finds plenty of food 

 near at hand to 

 nourish it during its 

 growth.
