Robber Fly (family Asilidae) – as perfectly stated in the Kaufman Field Guide to Insects of North America, these incredible flies “are to other insects what falcons are to other birds: swift predators on the wing.” This one captured a rather large stink bug for its meal. They have really showed up in force over the past 2 weeks. Photo by Glenn Marangelo on 7/4/16 in Missoula, MT.
