When people say that mosquitoes swarm in a place 

 they generally refer to the insects in the house in which 

 they happen to be staying (which is quite a different thing 

 to the place, i.e., the town or locality). They are also 

 generally speaking of Culex, which, I think, hum more 

 than Anopheles. Moreover, the "swarm" generally really 

 means only some dozen, or even fewer insects, which are 

 attracted by the teller of the tale. One or two pertinacious 

 mosquitoes often give a casual observer the impression of a 

 swarm being present. 



All these facts make it a difficult matter to arrive at 

 any really correct estimate of the actual number of mos- 

 quitoes existing anywhere.
