I was intrigued by this fly whilst walking my dog early one morning in late July. It was relatively slow moving and stuck around the same plant for a few minutes. It was the size of a large housefly. I encountered it on a mowed walking path near some grain fields at the edge of state forest land, in the Finger Lakes region of New York State. What is this delightful creature?
This is a parasitoid Tachinid Fly or Bristle Fly, but we are uncertain of the species as there are many similar looking species in this very large family.
