or seashore during the 

 summer. (2) Anopheles 

 (a-nof 7 e-lez) is the scien- 

 tific name of a second 

 kind of mosquito, which 

 is also generally distrib- 

 uted, but is not so 

 numerous as the Culex. 

 The Anopheles often 

 carries in its body the 

 germs that cause the 

 disease called malaria. 



(3) Stegomyia (steg-o-mi'ya) is a mosquito common in the 

 southern part of the United States. It is the insect 

 which carries the germs of yellow fever from one person 

 to another. 



It is fortunate that the mosqui- 

 toes have so many enemies. The 

 " wigglers " are preyed upon by the 

 larvas of the dragon flies, by small 

 fish, and by water beetles; while 

 the adults are eaten by nighthawks, 

 martins, bats, and dragon flies. 

 Certain diseases caused by plants 

 attack the adults and kill them in 

 great numbers. The number of 

 mosquitoes can be greatly reduced 

 by destrojdng their natural breeding 

 places in old rain barrels, watering 

 troughs, boxes that may hold water, 

 pails, eaves troughs, and sink holes. 

 The larger breeding places are 

 sluggish streams and swamps. 

 Draining these is the most effective
