Abstract
Tabanus nigrovittatus Macquart collected on a ditched tidal saltmarsh and adjacent upland at Leeds Point, NJ, are autogenous during the first ovarian cycle. Fat body from larval stages was depleted with maturation of the follicles during the first autogenous cycle. Following initial oviposition, parous females enter ovarian diapause and the second ovarian cycle is gonotrophically concordant. A duality of feeding on blood and/or nectar sugars was noted. Blood was directed to the midgut and sugars to the crop. T. nigrovittatus females are primarily large mammal feeders and only parous females imbibe blood. Sugars are not directly responsible for follicular maturation.
