The following is substantially the authors' abstract. A tidal marsh with drainage ditches in New Jersey contained a variety of microhabitats that influenced the distribution of Tabanid larvae. Population levels of larvae of Tabanus nigrovittatus Macq. and Chrysops spp. were highest below mean high-water level on gently sloping banks where cord grass (Spartina alterniflora) was about 2 ft tall. T. lineola F. and an unidentified species of Tabanus occurred mostly at higher soil elevations where short marsh grasses grew. Evidence strongly indicates that females oviposit primarily on vegetation of a certain height, and this choice of site influences resulting larval distribution.
