This insect is very large. It was at least approx
1" long. Looks like a fly, buzzed like
a fly. Have never seen a fly (if this is what it
is) this large on our southwestern Wisconsin farm.
Thanks in advance.

Hi Doug and Cindy,
This is a female Black Horse Fly, Tabanus atratus. The female,
which can be identified by the space between her eyes, is
the biting sex.
