After a number of sections devoted to general phases of entomology 
such as the relationships of insects to each other and to 
other invertebrates, the color of insects, the four stages 
of an insect’s life history, and the seasonal activity of 
insects, a series of exhibits is given which shows the principal insects 
of special situations and plants. Under the former heading we note 
aquatic insects and those associated with decaying material. 
The exhibits concerned with insects associated with special plants 
lay emphasis upon those of economic importance and are followed by a 
study of household insects, insects and disease, and insecticides. It is 
shown that man’s efforts to combat noxious insects is supplemented by 
the activities of lower mammals, birds, fish, reptiles, and of insects 
themselves.
