INSECTS

After a mini Iter of sections devoted to general phases of entomology 

 such as the relationships of insects to each other and to other inverte- 

 General brates, the color of insects, the four stages of an insect's 



Information Uf e 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 are supplemented bj- 

 the activities of lower mammals, birds, fish, reptiles, and of insects 

 themselves. 



Although certain insects destroy plants, some plants destroy insects. 



These and other eco- 

 logical interrelations of 

 insects and plants, in- 

 cluding pollination, are 

 shown on the east side 

 of the hall.

 makers, and other sorts 

 of laborers. The mak- 

 ing of silk is one of the 

 principal insect activi- 

 ties, and several sec- 

 tions are devoted to 

 silk, looking at it from 

 both the entomological 

 and the human view- 

 points. 



Following this, such 

 subjects as art, the 

 Bible and other litera- 

 ture, medicine and superstition in their relation to entomology are 

 treated. Photographs and short biographies of prominent entomologists 

 of the past are given. 



Evolution is a large subject, but the principal points involved in the 

 present-day theories are illustrated in a series of sections treating
