While on vacation, I stopped at the Great Salt Lake in Utah. On the shores of the lake, there was these flies that were about 1 1/2 inches in length and were large enough to cast a shadow as they were flying. I am somewhat familiar with insects but I haven’t seen any like these before.

Dear Brandon,
This is a Robber Fly in the family Asilidae, and we will attempt a more specific identification later today.
