I saw this large, all black insect flying outside our house early yesterday morning. It flew fairly slowly and landed near our garage. It seemed to have almost a “matte” finish . And it was about an inch long. Any idea what it is?

Hi Adam,
This is a Black Horse Fly,
Tabanus atratus, and the space between the eyes indicates she is a biting female.

    We just found one of these on our pool deck in Eastern Massachusetts. How bad is the bite from one of them?

    Got bitten in Jacksonville, Florida. The bug is the same color as matte black bumper on vehicle as I just saw again Today after I got chomped twice three days ago.
    The wounds swelled, still itch & with blood scars formed.
