After posting a shot of this situation the other day that focused on the prey, here's the predator. I find robber flies fascinating-- these large Dipterids take on prey that approaches them in size, and then fly around with it as they consume their meal. Gruesome and amazing! The species here was identified using the Seek app... I don't know enough to be able to dispute it, so I'm using the label. If you have other ideas, let me know. Taken at Horn Prairie in Fayette County, Illinois.

The Asilidae or Robber fly, also called assassin flies, are powerfully built, bristly flies with a short, stout proboscis enclosing the sharp, sucking hypopharynx. They are notoriously aggressive predators who feed mainly or exclusively on other insects ranging from other flies to beetles, butterflies. moths, various bees, ants, dragon and damselflies, ichneumon wasps, grasshoppers, and some spiders. As a rule they wait in ambush and catch their prey in flight.
I am indebted to leif_85 for identifying this insect for me.

Here a robber fly was busy eating a fly. I took this shot in our terrace garden First time I saw this insect.

The Asilidae are the robber fly family, also called assassin flies. They are powerfully built, bristly flies with a short, stout proboscis enclosing the sharp, sucking hypopharynx. The name "robber flies" reflects their expert predatory habits; they feed mainly or exclusively on other insects and, as a rule, they wait in ambush and catch their prey in flight.
Thanks everybody for the visit and kind comments!
