    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.t 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.
