THE BREEDING-PLACES OF 

 ANOPHELINES 



Larvae should be sought for in the most 

 diverse situations and, after being examined and 

 described, be allowed to hatch out. New species 

 of Anophelines are often obtained in this way. It 

 is .the case in India, and almost certainly will 

 beiound to be so in other countries, that certain 

 kinds of breeding-places are preferred by certain 

 species.* A collection of larvae made from shallow 

 puddles will be found to yield quite a different 

 set of species to one made from a streamlet or 

 pool full of vegetation, even though close to the 

 puddles (Fig. 58). 



The following tabular statement gives the 

 more common situations of Anopheline breeding- 

 places and the species, as far as known, found in 

 each. It is obvious that a great deal of work 

 yet remains to be done. 



1. Foul puddles near habitations M. rossii 



2. Clean puddles without much 



alga and often turbid with 

 suspended matter : — 



(a) Pits and puddles near houses Ip' '^ ^^V 



* Thus M. lutsi is said to breed only in the water'collected 

 in the leaves of the parasitic Bromeliaceae, and N . annulipes is 

 said to breed in the sea.
