Tabanus superjumentarius Whitney Tabanus superjumentarius Whitney (1879:37). Type-locality: New Hamp- shire, Milford. Moderate size (16 mm); eyes bare; thorax with grayish white pile; wing yellowish, becoming deeper colored anteriorly, especially along veins and in costal cell; fore tibiae uniformly dark; abdomen black with small median white triangles on second to fifth tergites, triangle on second very small or some- times absent (Fig. 178). Male eye fac- ets distinctly differentiated; thorax with brownish pile; eyes bare. The larvae (Fig. 204) have been tak- en from mud and moss along stream banks (Pechuman 1972; Teskey 1969). In Illinois adults appear at the be- ginning of June and have been collect- ed until early July. T. superjumentarius is a northeastern species, extending from Alabama to New Hampshire and west to Missouri (Fig. 254). This species has been col- lected from only one locality in Illinois.
