28 THE FLORIDA ENTOMOLOGIST 
where in southern Florida. On the writer’s second visit to the 
key in company with Capt. L. Cochron, many specimens of 
Aedes taeniorhynchus, the brackish water mosquito, were col- 
lected. This was the only species of mosquito encountered on 
the key. Mosquitoes were not present on the boat while ap- 
proaching the key from the north, but the minute we reached 
shore by means of a smaller boat carried with us, we were at- 
tacked. The writer‘s first impression on landing was not in the 
least encouraging; that, as reports had led him to believe, he 
would possibly find a solution for combatting the brackish water 
mosquito in Florida. He was not, however, greatly surprised 
when he did find plenty of mosquitoes there. The writer sur- 
veyed the entire key and stirred up mosquitoes wherever he 
went. In the mangrove the mosquitoes were quite plentiful, 
and in walking through the grass and shrubs, mosquitoes 
were encountered. These observations were made on October 
5, the day being bright and quite warm. No doubt the mosqui- 
toes would have been more numerous during the night. It is 
the writer’s belief that mosquitoes do not occur in as large num- 
bers on Bamboo Key as on Key Vaca or Grassy Key as well as 
some of the other keys in the vicinity. Bamboo Key is more or 
less wind swept. The vegetation is not as dense nor as high and 
hence does not afford nearly the harboring conditions for mos- 
quitoes as the other keys which are covered with a much denser 
growth of mangrove and high growing trees and shrubs. Again 
mosquitoes were not found breeding on the key as they were on 
the other neighboring keys. It appeared that the mosquitoes 
occurring on the key migrated there from adjoining keys to the 
south and southeast, the prevailing winds aiding their migra- 
tion from those directions. Bamboo Key might have been free 
from mosquitoes at one time but this is not true at present. It 
may be possible, however, that Bamboo Key is comparatively 
free from mosquitoes for very short periods during the summer 
months when mosquitoes are plentiful on some of the other keys. 
This would perhaps depend on the weather conditions at the 
time, and whether the wind was in a direction very unfavorable 
for their migration to the key.
