Wyeomyia smithii, the pitcher plant mosquito, is an inquiline mosquito that completes its pre-adult life cycle in the phytotelma of—that is, the water contained by—the purple pitcher plant, Sarracenia purpurea. 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.[1]

W. smithii is not a pest mosquito in general. The northern US population does not consume blood at all, while the southern US populations only consume blood after laying an initial egg batch;[2][3] even then they appear disinterested in feeding. In fact, it is the only known mosquito to have both obligatory biting and non-biting populations in the same species.[4]
