Again NEWSTEAD (1910) records as follows from the Amazon 
region : « Great numbers were found in large puddles in the open, 
in association with Anophelines and other Mosquito larva, although 
there were houses with suitable receptacles within 50 feet of 
these habitats. They occurred also im large, deep collections 
of terrestrial water, averaging 3 feet in depth. On one occasion 
swarms of larva were found in a barrel of water containing the 
macerated and putrid remains of a number of frogs, upon whose 
carcasses they seemed to have been thriving ». 
In Para, DURHAM (1901) records its habitats as follows : « Casual 
water in vessels, etc., in and about houses, such as buckets, tins, 
wash-tubs, rain-gutters, ant-guards, larger and deeper collections 
of water as casks and hogsheads full of rain water. = in the 
bilge water of barges and lighters, and on the S. S. Viking ». 
Further DURHAM says it is« not founds in cesspools, stable runnings 
or natural puddles in forest or streets ». 
Low, writing from the West Indies, states as follows: « It is 
essentially a domestic species, breeding in water barrels, tanks, 
tubs, fountains and other collections round houses. It is very 
commonly found with Culex fatigans. I have never found it in any 
other situations such as in the country collections of water 
favoured by Anopheles and other Mosquitoes, which may be termed 
wild Mosquitoes in contradistinction to the domestic (1) ». 
In Gambia DUTTON (1903) found this Gnat breeding in a tub 
of water, in wells and in a canoe. 
In Jamaica GRABHAM (1905) found it in tanks, tubs, wells, 
fountains, empty tins and calabashes. 
In New Orleans it was found most abundantly in the large round 
water cisterns used at the back of every house. 
BALFOUR has noticed that they will breed in the bilge water and 
tanks on the Nile steamers. 
Speaking generally this insect breeds in any small or moderately 
small collection of water near man’s habitations, especially 
artificial collections of water, such as in jars, tins, calabashes, 
cisterns, vats and tubs and on board ships. But at the same time 
we see it may go to larger and natural collections of water, but 
that such is unusual.
