Again, earlier in March while in the interior of the woods exposing 
myself to the attacks of Anopheles , I dislodged some mosquitoes from 
a young cypress tree. Upon closer examination I observed an A. 
quodrimaculatus female resting among the twigs. For several houi *9 
I repeated this experiment, vigorously shaking young trees in the 
cypress brake, and counted several mosquitoes, apparently anophe- 
lines, which were dislodged from their resting places. On the two 
following afternoons I brought a saddle horse to an open place near 
the cypress brake and in 30 minutes succeeded in collecting 24 
Anopheles that alighted on the horse. 
The evidence offered from the investigation thus far would seem 
to indicate that the majority of the mosquitoes captured probably 
hibernated in the denser portion of the woods. Here, protection 
from unfavorable conditions of temperature, winds, and moisture 
would be better assured. Doubtless, with suitable rise of tempera¬ 
ture, anophelines become active, biting men and horses in the woods, 
being transported in a measure by these natural vehicles out of the 
woods to the near-by dwellings. Here they would again seek shelter, 
selecting the most suitable substitute for trees, namely, the large 
timbers under the flooring of the house, where moisture, darkness, 
and wind protection could be obtained. Here, upon the under¬ 
structures, the anophelines were discovered in a quiescent state, the 
degree of dormancy depending on the time of day and the tempera¬ 
ture. By the aid of the electric torchlight, these mosquitoes were 
studied under many houses, beginning early in the morning and 
throughout the day. From a dormant, sprawling condition in the 
cold forenoons, a gradual change of attitude and location was noted. 
Incidentally it was observed that the well-known attitude of “ sprawl¬ 
ing” was rarely assumed when the temperature was above 9.0° C. 
The usual attitude of the two species, A. quadAmaculatus and A. 
punctipennis , under the dwelling was seen to be with the body held 
nearly parallel to the perpendicular plane, close to the flooring with 
the head directed upward and the caudal end slightly raised. When 
the weather became slightly warmer, or when disturbed from the 
normal attitude, the mosquitoes were found suspended from above, 
nearly at right angles to the flooring. 
A perceptible shifting toward the warmer and lighter side of the 
house was observed as the morning progressed. By remaining quiet 
for 30 minutes or longer, the observer was aware that the mosquitoes 
shifted from the understructures to the open spaces below. One 
would fly a meter or two, alighting on a beam near the outer wall 
of the house. If the weather toward noon was distinctly warmer, 
mosquitoes were seen to fly from beneath the dwelling into the open 
and in the direction apparently of the nearest trees.
