Robber Flies of North Dakota

Based on Fisher and Wilcox's Catalog 1997 (unpublished). Not all species have been verified but may occur based on presently known geographies. Subtribes are not shown. The large Efferia genus has been split into new genera by South American Asilid scientist Jorge Artigas. This split is not accepted by all fly guys apparently. I have put the new genera in [ ] under that genus.
