ArT, 1. MOSQUITOES OF THE UNITED STATES—DYAR. i 
eggs are laid on the still, dry, newly opened leaves, and hatch when 
water collects in them. 
The mosquito is rarely met with except by breeding from pitcher- 
plant leaves. It has not been recorded as biting; but as many of the 
tropical species attack warm-blooded animals, this may be found to 
do so. 
Distribution —Canada to Alabama, probably coextensive with the 
range of the host plant, Sarracenia purpurea.

Tribe CULICINI. 
This tribe includes the bulk of the mosquitoes, and all of those of 
typically northern distribution. Only the lowest members, such as 
Orthopodomyia, Megarhinus, and the lower subgenera of Aédes, live 
in water in plant tissues, such as the tree holes; most of the species in- 
habit ground puddles. The species and genera are variously differ- 
entiated. Aédes inhabits temporary puddles, especially water left 
from the melting snow in spring, and these species have in general 
but a single annual generation. Culex and Culiseta inhabit pools of 
a generally permanent character, and overwinter as adults. <Ano- 
pheles larvae are surface feeders, and consequently the character of 
the water makes less difference to them. They have been found in 
all sorts of water, even in running streams, but the different species 
are variously restricted.
