How a Wiggler becomes a Mosquito. While a wiggler is in 

 the form of a pupa, wings and legs are growing beneath the 

 skin, and its body is changing to the body of a full-grown mos- 

 quito. When the change is complete, it floats on the water, 

 its skin splits down its back, and a full-grown mosquito crawls 

 out and flies away, leaving an empty skin on the water. 

 U'atch the wigglers till one comes out of its pupa case. 



How Mosquitoes Eat. Look carefully at the mosquitoes that 

 come from the jar of wigglers. They have long slender bills 

 through which they suck their food. Some of them have feath- 

 ery feelers on their 

 heads, and can not use 

 their bills for piercing 

 the skin or for biting. 

 These are the" father 

 mosquitoes, and are 

 sometimes called fuzz- 

 bWs. If they eat at 

 all, they must sip liq- 

 uid food as house flies 

 do. The mosquitoes 

 that bite us are all 

 mother mosquitoes. 

 Their feelers are so 

 small that you can 

 hardly see them. MOTHER Mos Q ulTO (Magnified) 



Kinds of Mosquitoes. There are many kinds of mosquitoes, 

 differing somewhat from one another in looks and in their 

 mode of life, but all of them spend the early part of their lives 

 as wigglers under water. 



The Harm done by Mosquitoes. When a mosquito sucks 

 blood, it leaves behind a bit of poison which causes a raised 

 spot and an itching on the skins of some people.
