Habitat
Aquatic including floodplains and temporary water pools. As a floodplain mosquito , are laid in dry areas that subsequently flood.
Distribution
North America. Present in distribution records, though specific range boundaries within the continent are not detailed in available sources.
Diet
Larvae are obligate , feeding on other aquatic insect larvae including other mosquito larvae. This has been observed in congeneric and is characteristic of the .
Life Cycle
are deposited in dry floodplain areas and hatch following rainfall that floods the surrounding wetland. Larval development occurs in aquatic environments.
Behavior
Larvae exhibit predatory strike involving sudden neck extension to launch the toward prey, with and associated brushes spreading open and snapping closed on impact. This harpoon-like action is generated by pressure buildup and rapid release in abdominal segments. The strike duration is approximately 15 milliseconds.
Ecological Role
As an obligate in larval stages, contributes to regulation of other aquatic insect including other mosquito larvae.
Human Relevance
females may bite humans; related in the are known as aggressive biters. Potential capacity not specified in available sources.

More Details
Predatory strike mechanism
The larval predatory strike involves coordinated anatomical actions: neck extension, and brush spreading, and rapid closure upon prey contact. This represents a fixed-action pattern completed in approximately 15 milliseconds.
