This little fellow joined me on my lounger as I was enjoying the beach. Would you be able to tell me what it is?
Can you please provide us with an approximate size since “little” is quite relative. At first, upon viewing the head on view, we were convinced this was a Hanging Thief, a species of Robber Fly in the genus Diogmites, however, upon seeing the view from the rear, we have our doubts. This Robber Fly most closely resembles a species in the genus Saropogon, however, BugGuide only has sightings in the Southwest, and we cannot locate any information if that species is found in Canada. You can compare your fly with images posted on BugGuide. Here is the online key to the genus Saropogon, but alas, ranges of different species are not included. We will contact Eric Eaton for his opinion, and we might try to elicit assistance from other experts, Dr Robert Cannings and Eric Fisher.
Thank you for your help. This robber fly was about 1-1.5″ long. It does look like the Saropogon luteus.

Sorry for the long, long delay. I think this is Diogmites basalis, the only Diogmites that occurs in Canada, as far as I know. As you suggest, no Saropogon species comes close to Canada, especially in the East.
