Hey there,
When I was in Kennedy Meadows, CA I saw this huge fly looking insect. I think if may be a species of Robberfly, but i am not positive. I believe it was around last August when I saw it. Think you can help me out? Thanks a bunch!

Hi Jared,
This is indeed a Robber Fly.  Our quick search this morning did not turn up a species match, but it reminds us of the genus
Promachus pictured on BugGuide as well as the genus Proctacanthus also pictured on BugGuide.  Both genera are also pictured on this wonderful Robber Fly website.  Perhaps one of our readers will be able to assist with this identification.
