bristles which serve as receptacles in which the bee carries 

 the pollen to the hive. The lower lips of honeybees and of 

 bumblebees are long, to enable them to suck nectar from 

 flowers. 



The maxillse of many butterflies and moths have been 

 developed into long probosces to enable them to procure 

 nectar from deep flowers. This is 

 well shown in those large hawk moths 

 that frequent honeysuckles at dusk. 



Many grasshoppers are colored like 

 the soil on which they live. This is 

 well shown in the case of those grass- 

 hoppers that are so frequently found 

 along dusty highways. It is diffi- 

 cult to find one of these insects after 

 it alights, so closely does it resemble 

 the soil. 



The bodies of fleas are greatly com- 

 pressed and these insects are thereby 

 enabled " to glide through the nar- 

 row spaces between the hairs of their 

 hosts." 



The so-called flat bugs have thin flat bodies, which 

 enable them to live between the bark and wood of decaying 

 stumps and logs. 



Katydids have green wings with veining to resemble 

 leaves. The walking sticks greatly resemble sticks. 



A most interesting line of field work may be instituted 

 and carried on throughout nearly the whole year, especially 

 in the southern states, on the habits of insects and their 

 adaptations to their environments.
