B, s^,) can often be seen a little above the second pair of 

 legs. There is also one more pair on the first ring of the 

 thorax. 



Through the breathing holes air passes to the wonder- 

 ful sets of air tubes and air sacs found in every part of 

 the grasshopper's body. Fifty-three of these tiny bal- 

 Inons have been counted in the head alone. A body 

 made so light and buoyant is easily carried through the 

 air by the strong wings. 



The baby grasshopper, called the larva, is like its 

 mother, but has no wings. In order to grow it must 

 throw off its outer coat, just as the yoimg lobster does. 

 After it has done this three times little wing-pads appear 

 on its back, and it is now called a pupa. Twice more it 

 casts off its coat, and now it is the full grown imago, 

 ready for flying or jumping. 



The note of the grasshopper is produced by rubbing 

 the small teeth on the inner side of the thigh of the hiud 

 leg against the veins on the outer side of the fore wing, 

 or wing-cover as it is often called. It is easy to show 

 how this is done by drawing a comb over the edge of a 

 piece of stiif paper.
