I came across this bug when I was walking my dog in a field and I’ve never seen anything like it before. It’s summer here and the bug was a little over an inch long. Any ideas??

Female Western Horse Fly

Dear Curious,
This is a female Western Horse Fly, identified by the gray thorax and the space between her eyes.  Only female Horse Flies are blood suckers, and though humans are not a normal host, a hungry opportunistic female Western Horse Fly might bite a person if no livestock are available.
