Horse Fly

Strafing Horse Flies

While taking photos today of willow pinecone galls for a BYGL Alert, I was constantly strafed by a maniacal horse fly (Tananus spp.).  These hefty flies belong to the family Tabanidae which is the largest family of bloodsucking insects with over 4,500 horsefly species known worldwide.  There are several species in Ohio ranging in size from 3/8 - 1 1/8" in length.  The crazed fly buzzing me was T. abdominalis.  It doesn't have a common name other than #@%%# fly!  At least, that's what I called it.
