20 MOSQUITO 



SUPPLEMENTARY WORK 



The Habits of a Mosquito Pupa. — When a wiggler is about 

 to become a pupa, it sheds its skin. A wiggler usually spends 

 two or three days as a pupa and eats nothing during that time. 

 It no longer breathes by the tail end of its body, but by means 

 of two tubes that extend upward from its back. It moves 

 about freely. 



3. THE FULL-GROWN MOSQUITO 



Observation. — How many days did you keep the 

 wigglers before one changed to a winged mosquito ? 

 Look at a mosquito. What is the shape of its head ? 

 What is the shape of its bill ? What is the shape of 

 a mosquito's thorax ? What is the shape of its ab- 

 domen ? Is the thorax sharply divided from the 

 abdomen ? How many wings has a mosquito ? What 

 is their shape ? To what part of the body are they 

 joined ? How many legs has the mosquito ? How 

 many joints do you see in a leg ? 



Drawing. — Draw a picture of a mosquito as you 

 see it when you look at it from one side. Make the 

 picture three or four times as large as a real mosquito. 

 A mosquito is somewhat humpbacked. Draw the 

 head and body in the shape that they really are on 

 the mosquito. 



Composition. — Write a description of a mosquito.. 

 Write it in paragraphs like those in the outline for 

 the composition on the house fly.
