XL NEST OF A MUD WASP 



Material. Nests of mud wasps brought by the pupils. They can be 

 found on piazza ceilings, and under the roofs of attics, barns, and out- 

 buildings. 



Observation. What is the size of the mud wasp's 

 nest ? What is its shape ? What is its color ? Of 

 what is it made ? How many cells are in it ? How 

 are the cells arranged ? Do you find their doors ? 



Break open one of the cells. How thick are its 

 walls ? How large is the cell ? What is its shape ? 



Do you find a young wasp in an opened cell? Is 

 it a larva, a pupa, or a winged wasp ? In the cells 

 you may also find the bodies or remains of insects on 

 which the young wasps fed. What kind of insects 

 were they ? 



Drawing. Draw a picture of the mud wasp's 

 nest. Draw the outline of the whole nest with heavy 

 lines. Then with lighter lines draw such parts of the 

 separate cells as you can readily see, for the cells do 

 not always show plainly on the outside of the nest. 



Composition. -- Write a description of the mud 

 wasp's nest that you examined. Make a paragraph 

 about the appearance of the whole nest, another para- 

 graph about its cells, and a third paragraph about 

 what you find in the cells.
