The species is not an early one and the first outdoor captures were made June 30 and as late as September 9. Some collections have been recorded from New Brunswick, Little Ferry, Hackensack, and Great Piece Meadow. The species seems to confine itself to wooded areas exclusively and to prefer those which are low, swampy, and cold. None of the collections made indicate that it is at any time a house mosquito.
As to the matter of hibernation nothing is really known so far as I am aware. It is probable that the winter is passed in the egg stage and possible that the egg may become dry at times ; but none of the other species known to me as egg hibernates make so late a start in the spring as this species seems to do.
The egg laying habits have been observed by Dr. J. W. Dupree, of Baton Rouge, Louisiana, and recorded by Professor H. A. Morgan. A female specimen captured April 30 was permitted by Dr. Dupree to feed upon his hand until fully engorged. On the morning of May 1 forty eggs were found, some at the bottom of the glass containing the water, while others were resting upon some fibers of cotton which had accidentally fallen into the vessel. Dr. Dupree thinks it altogether likely that the eggs, which are deposited singly, under normal conditions rest upon floating debris.
