Tachnid Fly  (three photos)
Genus Cylindromyia

Cylindromyia tachnid fly
Cylindromyia are parasitic on other insects, especially stink  bugs. They lay eggs
directly on an insect and when the eggs hatch, the larvae feed off the insect.  Icky!

This genus of tachnid fly looks very much like a wasp and the mimicry may
 help keep them alive longer.  After all, who wants to take on a wasp?

I found this skinny little fly in the Jordanelle Dam Wetlands
in Wasatch County, Utah.
