Life Habits 



To J. Turner Brakeley belongs the credit of having tirst worked 

 out many of the life habits of this mosquito. Mr. Brakeley 's ob- 

 servations, as recorded by Dr. J. B. Smith/ covered a period of i 

 year and demonstrated: (i) that there is only one brood; (2) the 

 larvae hibernate and remain attached to the mass of roots of aquatic 

 plants even when the water freezes solid; (3) neither larvae nor

pupae normally ever come to the surface; (4) egg-laying begins 

 while a considerable percentage of the previous season's larvae are 

 still immature; (5) adult mosquitoes begin to appear early in June 

 and continue to come in noticeable numbers throughout the season. 



The irritating mosquito breeds mostly in swampy places. The 

 habit of the larvae and pupae of securing their oxygen supply with- 

 out coming to the surface renders the immature stages of this spe- 

 cies radically different from nearly all others.
