I don’t think so!

A horse fly, possibly Tabanus calens, was spotted after a long photowalk at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA. This individual is a female, as indicated by her eyes.

Males have eyes that meet along a seam down the middle of the head (holoptic eyes); females have eyes that are well-separated. Source Credit: Benjamin A. Coulter, member of the BugGuide group on Facebook.

A wider view shows the horse fly is perched on my Honda Civic, just above the handle of the driver’s side front door. Male horse flies don’t bite; females bite, painfully!

Adult horse flies feed on nectar and sometimes pollen. Females of most species are anautogenous, meaning they require a blood meal before they are able to reproduce effectively, if at all. Much like male mosquitoes, male Tabanidae are not ectoparasitic and lack the mouth parts (mandibles) that the females use in drawing the blood on which they feed. Most female horse flies feed on mammalian blood, but some species are known to feed on birds or reptiles. Some are said to attack amphibians as well. Source Credit: Horse-fly, from Wikipedia.

I shooed the fly away from the front door handle, but she didn’t go far. She landed on the Honda logo on the trunk of my car — still too close for comfort! I’m happy to report I was able to get into my car without being bitten.
