Your letter to the bugman:  I caught this aggressive little guy alone when he landed on a plant near a riverbank in Tumwater, Washington – near Olympia. After hours of entomological research I cannot for the life of me find something with a thorax like this, but “furry”.

Robber Fly

Dear out-of-options,
Your identification research did not prove successful because, though it resembles a stinging insect, this is not a Bee nor a Wasp in the order Hymenoptera, but rather a predatory Robber Fly in the order Diptera and the family Asilidae.  It sure looks to us like it might be the Bee-like Robber Fly
Laphria columbica which is pictured on BugGuide and reported from Washington.
