52 THE MOSQUITOES OF NEW JERSEY 



toothed spines from sixteen to twenty-four in each. Spines have from 

 one to five teeth, may be either slender or stout. Ninth segment small, 

 almost square, completely ringed by chitinized saddle. Dorsal tufts 

 normal; ventral brush thick, short hairs ; tufts confined to barred area. 

 Anal gills very short, often no longer than wide. 



HABITS OF THE EAELY STAGES 



When the eggs become covered with water by rains or by the tides 

 the larvae develop and emerge, often within a period of minutes rather 

 than hours. A week is all that is necessary to bring the larva to ma- 

 turity, and the pupal stage is short or long, according to temperature. 



At Anglesea young larvae were taken as early as March 5, though 

 development at that period is slow. On March 12 larvae were more 

 abundant and evidently developing generally. At that time the tempera- 

 ture of the water in which larvae occurred ranged from 42°r. to 50°F. 

 At this temperature microscopic life multiplies slowly and the wriggler 

 food supply is limited ; therefore this first brood of larvae dawdles along 

 for a month before adults are ready to emerge. Breeding continues until 

 early October ; but after that few eggs remain to be developed, except 

 for the spring following. If the wriggler succeeds in reaching the pupal 

 stage before a pool dries up it is usually safe, for the pupa will live 

 twenty-four hours in soft mud and develop as an adult ; indeed not more 

 than twelve hours is really needed. Larvae more than half grown will 

 survive in soft mud a few hours, and if the pool is then refilled by rain 

 or tide will revive and complete their transformations. 



In its actions or method of feeding the larva offers nothing out of 

 the usual course, and it is readily subject to the effect of oils and other 

 coverings. As a rule the water it inhabits is tolerably clean, but it is 

 able to sustain itself in quite foul and fermenting pools.

DISTRIBUTION AND CHARACTERIZATION 



[Atlantic Coast of America, exclusive of Antilles and on Pacific Coast 

 from southern California southward. Commonest coastal species in 

 warmer parts of continental America. Replaced by closely related 

 forms in Antilles, on west coast of South America, on some Pacific Is- 

 lands. Trapped 7,701 females in New Jersey.]
