In this microcommunity of bacteria, rotifers, protozoa, and midges, W. smithii is the top-level predator; its presence determines the bacterial species diversity within the pitcher.

[4] The life cycle of Wyeomyia smithii begins in either late spring or early fall when the adult female lays her eggs in the phytotelma of a purple pitcher plant.

Wyeomyia smithii females will produce a clutch of fertilized eggs generally within two days of sexual maturity.

For the initiation of not developing, insects pass through a "sensitive period" during which day length is interpreted as long or short, which results in a diapause/no-diapause response.

Wyeomyia smithii oviposits into and completes their entire preadult development only within the water-filled leaves of the carnivorous pitcher plant Sarracenia purpurea.

There is little fluid secreted by this plant in comparison to the rainwater it collects in its pitcher, which dilutes the solution and creates a more habitable environment for outside organisms.

The plant's adaptation allowing it to host diverse life is an advantage to the mosquito because its larvae prey upon those organisms.

The pitcher plant is filled with water and this is a type of environment that is used as a location for female mosquitoes to lay their eggs.
