no means of classify- 

 ing larvae accurately 

 except by rearing- them. 

 The same is true of pupae ; 

 but if the pupa is sus- 

 pended from a plant, it 

 is probably that of a 

 butterfly; if it lies in a 

 silky cocoon or in twisted- 

 up leaves, it is probably 

 that of a moth. Should 

 it be in the ground with- 

 out a cocoon, it may 

 emerge as a beetle or a 

 moth. If there be many 

 in a nest together, they 

 belong to Hymenoptera. 

 The figures of different 

 larvae and pupae will help 

 in classifying them. 



The following English 

 terms are generally used 

 for the larvae of different 

 groups : 



A hopper is the young 

 (nymph) of a locust or 

 grasshopper.
