2. THE MOSQUITO 

 (a) The Egg 



Observation. Look for the eggs of the mosquito, any time 

 in warm weather (April to October), on the surface of stagnant 

 pools. Look for them wherever the common wigglers are to be 

 found. Note. The eggs are laid in small rafts or packets, or 

 singly, in the case of anopheles, the malarial mosquito. They 

 float on the surface of the water. 



Conclusion. How are the eggs adapted to their habitat ?
