parallel to that wall like a house-fly ; but an Anopheles 

 mosquito usually rests with its body at a considerable 

 angle to the surface. We have seen Anopheles clinging 

 to the ceiling in a horse stall by their four front legs with 

 their bodies hanging almost straight downward. 



Moreover, the wings of all of the common Anopheles 

 are more or less spotted, while those of Culex are plain 

 and clear. 



BREEDING PLACES OF ANOPHELES 



It is quite as necessary to know the places in which 

 these mosquitoes breed as to know their life history, 

 if one wishes to destroy them before they become full- 

 grown. 



The common mosquito (C. pipiens) breeds in barrels, 

 tubs, cisterns, and other receptacles about the house and 

 is, therefore, known as the house mosquito ; but Anoph- 

 eles rarely breed in such situations. They choose a 

 ditch, a pool, or the shallows of a spring brook, creek, 

 or river for their breeding places. 



It is important to note that all these breeding places 

 are in water standing or running on the ground and only 

 occasionally in barrels, buckets, or other receptacles about 

 dwelling-houses. In this respect the malarial mosquitoes 

 are quite different from the common Culex, which breeds 

 in almost any situation where it can find water.
