FIELD ZOOLOGY. 



Some harmful hemipters and their bird enemies 

 might be mentioned: 



Squash bugs 



Hawks 



Stink bugs 



House wrens 



Chinch bugs 



Quails 

 Meadow larks 



Scale insects 



Downy woodpeckers 



Bark lice 



Hairy woodpeckers 

 Nuthatches 



Seventeen-year cicadas 



Cranes 



Song sparrows 



Prairie chickens 

 Kildeers 



Brown creepers 



Chickadees 

 Brown creepers 



The order includes about five thousand species for 

 North America alone; and yet it is a comparatively small 

 order, the Coleoptera including more than eleven thousand 

 species, and that order falls far behind the order of the 

 flies in point of numbers. When the systematist says 

 species, he means kinds; so there are more than five 

 thousand kinds of bugs.
