WING FILE OF MALE CRICKET.

THE KATYDID. 



1. Examine the katydid as you did the grass- 

 hopper. See all the organs. 



2. AVhere is the ear? 



3. Find tlie apparatus with Avhich he makes the 

 sound ' ' Katydid. ' ' 



4. Find the ovipositor. Is it straight or curved? 

 Of how many parts is it composed? 



Additional Fact-s. 



The katydids are light green colored, like the leaves 

 among which they live. They are protectively colored. 

 The legs are more slender, and the whole body is more 

 loosely joined together than that of the grasshopper. 

 This may be associated with tlie fact that the katydid 

 does not fly so far nor so rapidly as the grasshopper does. 



The eggs of the katydid are laid upon or in the 

 edges of leaves, or sometimes between the bark and 

 stem of a shrub or twig. 



The katydid belongs to the family Locustidie.
