was in the forest. The eggs are deposited in curious little 

 brown packets, that may often be found under the loose 

 bark of fallen logs.

 and the Mantids, which are generally useful in that they 

 feed upon various sorts of destructive insects. 



OBSERVATIONS FOR PUPILS 

 SHORT-HORNED GRASSHOPPERS OR TRUE LOCUSTS 



1 . Get a few good-sized grasshoppers the larger the better. Kill 

 them in a cyanide bottle or by immersing in alcohol. Study the struc- 

 ture carefully to see if you can make out all the details mentioned on 

 pages 65-67 of this chapter. 



2. Collect a lot of grasshoppers in a meadow or pasture. How do 

 the young differ from the adults ? Rear a few in a vivarium, feeding 

 with clover or grass. 



3. Place a piece of sod in the bottom of a box or a wide glasr cylin- 

 der. Put a few full-grown grasshoppers in also. See if you get eggs 

 laid. 



4. Look up some of these references : 



The Insect Book, pages 332-335. American Insects, pages 136-147. Nature Bi- 

 ographies, pages 89-95. Life Histories of American Insects, pages 67-81.

Where and when the eggs are laid. 



What the eggs look like.

What the young grasshoppers look like. 



The growth of the young grasshoppers.
