Under some conditions the females do tiot 

 feed upon blood, e.g., A. maculipennts in England 

 (Theobald). 



Bancroft states that Nyss. annuUpes will 

 live for a month on dates, but only for three days 

 on bananas. 



Time of Feeding 



The usual time for feeding of Anophelines is 

 after dark, more especially in the early night and 

 before dawn. Occasionally some Anophelines may 

 be found biting in broad daylight, and Annett 

 and Button state that Anophelines feed readily in 

 certain parts of Nigeria by day. Possibly certain 

 species feed more readily by day than others. 



We have ourselves seen on rare occasions 

 M. rossii attempting to feed in the daytime, and 

 Gray, B.C. A., says ' that Ce. albipes when disturbed 

 will bite at any time of the day or night.' 



On the whole, however, the Anophelinae are 

 strictly nocturnal in their habits. Nor do they 

 hover around lamps as has been supposed. Of 

 A. bifurcatus, Blanchard states that it bites 

 fiercely at dusk, but at night practically not at 

 all. At dawn, however, it begins again, and it 

 bites at all times in shady places, outhouses, etc. 



Distance of Flight 



The maximum distance that Anophelines can 

 fly requires further study. In questions of flight, 

 the species of mosquito should always be noted. 

 Observations upon the flight of mosquitoes have, 

 so far, been vague and uncritical. With regard 

 to Anophelines on ships, it must be borne in mind 

 that they have not necessarily come from the land
