The land Columbus loved : bare feet and burros of Haiti

Abstract

Thier eggs, like those of the vellow fever mosquito to which they are related, are not laid directly in the water but upon dry ground where pools have been before. Heavy rains filling the depressions cause the eggs to hatch. Most northern kinds breed in puddles from thawing snow in the spring, and there is only one brood a year. The eggs, laid in summer. and late spring, wait over until the next year to hatch. Sometimes, though, when the depressions where they lie are filled by heavy summer rains, the eggs do not hatch, seeming to need a coid treatment first.Farther south and in desert regions, a brood of mosquitoes follows each heavy rain. Here the wiggler period is very short, sometimes less than two days, since this stage must be completed before the puddle dries up.
