any more info?
I couldn't find any descriptions or distinguishing characters of this species on the web - just checklist entries. How is it identified?

Body pattern and antennae
The dull bare unicolorous eyes and vertex without a distinct ocellar tubercle, puts in the genus Tabanus. The locality, Ontario, esentially limits it to one of 22 species. A great help as there are 108 spp. of Tabanus in NA. It then keys out to catenatus using Teskey’s key in “The Horse Flies......of Canada...”. Basically, reddish body with distinct but small white triangles and dark antennae.

Thanks
I added another reference, and a few additions re: size, range. Wings are not black!
