Tabanus sackeni
Tabanus sackeni is a species of horse fly in the family Tabanidae, described by Fairchild in 1934. Males and females exhibit distinct activity patterns: males are primarily collected at UV-light traps just before sunrise, while females show crepuscular host-seeking peaks and are caught in Malaise traps in the evening. Females frequently have large crop volumes after blood-feeding, and many dipping females are gravid. The species occurs in Canada and the United States.
