Cyrtopogon longimanus

Cyrtopogon longimanus Loew, 1874 is a Robberfly (Asilidae) known from North America. It is closely related to C. marginalis, also known from the eastern U.S. and Canada, sharing a puffed-up, shiny black scutellum, which lines-up with a series of shiny-black spots along the sides of the thorax with that species.
