48 INSECTS. 



When the nymph is fully grown, it crawls out of the 

 water upon some convenient rock or reed, and fastens its 

 feet firmly, preparatory to the last and most remarkable 

 transformation of all, the transformation which fits it 

 for an aerial life. 



Keep some of the largest nymphs, supply them with 

 proper food, and watch their final transformation. 



Make a series of drawings of the egg, of nymphs of 

 different sizes, and of the adult, of one species. This 

 will be a pictorial life history of the species. 



The dragon flies constitute the group Odonata. 



THE GRASSHOPPER. 



Haunts and Habits. A large gray species, properly 

 called the Carolina locust (Dissosteira Carolina), is abun- 

 dant by every roadside, 

 and will serve well for 

 class use. It may be rec-

killed with a cyanide bot- 

 tle. Nymphs will be found in the same situations as the 

 adults. They resemble the adults quite closely in form, 

 but are smaller, and lack fully developed wings. 



Collect nymphs in all stages. 



Collect adults of different species for comparison. 



Collect for dissection a few of the very largest speci- 

 mens obtainable, of any species. 



Study in the field (for the Carolina locust) : 



1. Its protective coloring. 



2. Its several methods of locomotion.
