As water depth increased, fourth instar larvae of the mosquito Aedes aegypti required progressively more time to reach the pupal stage, more individuals died or were disabled and the resulting adults were significantly smaller. Water depth affected females more severely than males and the developmental time of larvae was affected more than adult mass. Time spent by fourth instar female larvae in the feeding zone during the first five hours predicted the time to subsequent pupation. Thereafter, mean feeding time was a determining factor of subsequent adult mass. With increasing water depth, both the prepupal resting period and mean time spent in the feeding zone per feeding bout increased, whereas behavior frequency (determined by an activity index) decreased.
