This 12mm long horse fly (Tabanidae) bit me in my neck when I was out looking for subjects. I instinctively whacked it thinking it was a mosquito. It actually seemed to be more surprised than hurt by my treatment but I got the opportunity to snap a couple of shots of it before it went looking for less violent victims.
Here you see it cleaning its large beautiful eyes with the brushes on it's front legs.
Single, handheld exposure.
