Abstract: We marked and released approximately 253,000 females of this species and recaptured 585 of them (0.23 per cent). In these experiments we recorded natural dispersal as far as 5 miles downwind on the night of release and 15.75 miles downwind two nights later. As the chances against recapturing any particular specimen are enormous and increase with distance, it seems certain that this mosquito spreads beyond any of the recovery sites. Probably it travels 8 or 10 miles in two evenings, and we believe that it can spread in one generation, with the prevailing SSE winds, at least 20 or 25 miles from its breeding areas.
