Your letter to the bugman:  Hi, my sister sent me these photos of what looks like a furry dragonfly.  I did a bit of research and found that it looks similar to a red footed cannibalfly…. what do you think?

Robber Fly

Dear Astrid,
This is a large Robber Fly, judging by the ash seed used as scale, but it is not a Red Footed Cannibalfly, an eastern species.  It looks similar to this
Machimus species pictured on the Natural History of Orange County site, but we cannot state for certain that is a correct genus identification.
