REPORT ON MOSQUITOES. 469 



SOME FACTS ABOUT MOSOUITOES. 



1. There are over thirty species of mosquitoes in this part of the United 

 States. 



2. Different species have different habits, as do different birds and fowl. 



3. Some species are domestic — breeding in fresh water, flying short dis- 

 tances and habitually entering houses. Others are migratory, flying long 

 distances, and almost never (except accidentally) entering houses. The 

 latter are occasionally seen in South Orange. Most migratory mosquitoes 

 breed in salt water marshes. 



4. All mosquitoes breed in stagnant water, and require from one to three 

 weeks to transform from eggs to winged mosquitoes. 



5. The common house mosquitoes (Culc.v pipiens) are the most abundant 

 of domestic mosquitoes. 



6. The malarial mosquitoes {Anopheles) may breed in any sort of receptacle 

 or puddle holding water, and are the most dangerous domestic mosquitoes. 

 They never travel far from their breeding place. Ross, an eminent authority, 

 says 600 yards is about the limit. 



7. Mosquitoes do not breed in the grass, but tall grass forms a favorite 

 harboring place. A mosquito a day old is full grown — females three days 

 old may lay eggs. 



Salt marsh mosquitoes breed four and one-half miles southeast and five 

 miles east of South Orange ; these were present about ten days during 1903. 

 About August 2d, to 5th, with four days gentle east wind, the marsh 

 mosquitoes were very numerous in the fields and gardens for about five 

 days. They were not noticed by most people because they did not seek to 

 enter houses. They were also present July Sth to the loth. The Newark 

 and Elizabeth salt marshes are now being drained.
