Dear Bug Watcher,
The predator in your image is a Robber Fly, but we are not certain of the genus.  We will attempt to research its identity further.  The prey appears to be a Blow Fly, perhaps a Green Bottle Fly or some other member of the genus
Lucilia, a group that is well documented on BugGuide.
