Sure, maybe I'm paranoid, but as I snapped this guy's picture I swear he kept looking in my direction every time the shutter fired, just as you see here. I've seen wasps do this before, which is interesting because this little Argid Sawfly is actually related to the wasp family.
Taken at the Don Valley Brickworks, which is yes, near the
Don River.
