BROOK LIFE.

The grouse-locusts are commonly found in low, 

 wet places and on the borders of streams. They 

 prefer the broad gravelly stretches where there is 

 little or no vegetation, the low banks that are swept 

 by the water when the streams are high. They vary 

 greatly in color, their color being usually similar to 

 that of the soil on which they live. They are very 

 active, and hence difficult to catch without the use 

 of a net. In studying these insects in the field note 

 especially the protective nature of their colors. Pre- 

 pare one or more specimens for your collection by 

 spreading the wings so as to show the relative size 

 of the fore and hind wings. 

 Label them as follows : — 



Order Orthoptera (Or-thop'te-ra). 



Cockroaches^ Crickets^ Grasshoppers, and Others. 



Family Acridid/e (A-crid'i-dae).
