SOME FACTS ABOUT MOSQUITOES. 



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 

 distances 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 (Culex pipicns) 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 do- 

 mestic 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. 



8. Salt marsh mosquitoes breed 45^ miles southeast and 5 miles 

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

 1903. About August 2d to 5th, w-ith 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 5th to the 

 loth. The Newark and Elizabeth salt marshes are now being drained.
