House-Flies or Typhoid-Flies 75 



OTHER FLIES 



Occasionally other flies looking more or less like 

 the house-fly are seen in houses. Some of these 

 have the same type of sucking mouth-parts and 

 have habits very similar to the house-fly, but as 

 they are usually much less common and as nearly 

 all that has been said in regard to the house-fly 

 would apply equally well to them and as the same 

 measures should be adopted in fighting them they 

 need not be discussed further here. 



I have already called attention to the fact that « 

 a fly which looks very much like the house-fly is 

 sometimes found in the house and will often bite 

 severely. It has quite a different style of beak, one 

 that is fitted for piercing so it may suck the blood 

 of its victim (Fig. 51). As these flies often seem 

 to be more persistent before a rain the weather 

 prophet will tell you that "It is surely going to rain 

 for the house-flies are beginning to bite." 



These stable-flies, as they are called, are great 

 pests of cattle and horses in some sections. It is 

 thought that they are important factors in the 

 spread of some of the diseases of domestic animals, 

 and their habit of sometimes attacking human be- 

 ings makes it possible for them to carry certain 

 disease germs from animals to man or from man 

 to man.
