Robber fly, female
by: Moni

Yes, your insect is a robber fly. And from the looks of the pointed abdomen it is a female.
This looks like a fly in the genus Efferia, but without more information on size and other angles I am not sure. They are found east of the Rockies thru out North America. The larvae usually occur in soil or decaying wood feeding on eggs or larvae of other insects. The adults prey on other insects for food so are considered beneficial in the garden.

What a great photo! This fly looks nasty. Maybe he is after your china instead of your coffee :). Or, he could be a spy sent by Doug to find the best coffee there is...
