mosquitoes oe the year 



The first brood of salt-marsh mosquitoes, which usually 

 appears during the first half of May, came out in small numbers 

 along the lower Atlantic and the Blay coasts, and was scarcely 

 noticeable in northern New Jersey. 



The second brood appeared about the middle of June in the 

 south and about five or six days later in the north. In the south 

 this brood was large enough to migrate 25 miles or more back 

 into the pines. 



The third brood began to come out about the tenth of July 

 in Cape May County, appeared in Atlantic about the twelfth 

 and made itself felt in the north about the sixteenth. This 

 brood was large from the undrained salt miarshes and carried 

 far. Indeed, the number escaping from the drained marshes 

 was unusually large. 



The fourth brood emerged during about the corresponding 

 period in August. It was not so large as the preceding, nor 

 did it travel so far. 



The fifth brood began emerging from the tenth in the south 

 to the sixteenth in the north. Although not so general as was 

 the August brood, in limited areas the density was great and 

 the annoyance serious. 



The first, or May brood, was composed of A. cantator, with a 

 few A. sollicitans along the Delaware Bay coast. The second, 

 or June brood, consisted of A. cantator in the north and A, -sol- 

 licitans in the extreme south, with a mixture of the two species 

 between. The third, or July brood, consisted of A, cantator and 

 A. sollicitans in the north and A. sollicitans throughout the south- 

 ern two-thirds of the coast. The fourth and fifth broods were 

 mostly A. sollicitans, although A, cantator appeared from the 

 upper courses of the streams when bordered by salt marsh. 



In June and again in July the fresh- water swamp mosquito 

 appeared in large numbers, especially in July. Taking the season 

 as a whole, this species (A. sylvestris) has been the dominant 

 mosquito in point of numbers throughout the non-sandy section 

 of the seacoast.
