User's notes

I believe that this was a Robber Fly of the species Cerdistus exilis. This individual was very calm. I was able to take some handheld flash-assisted shots with a camera without disturbing it, I was even able to set up a tripod to put my camera on without making the fly scared. Even when I left the fly was still as this photograph shows it, on the trunk of this tree.
