Tiny Robber Fly  (five photos)
Genus Stichopogon

small robber fly
I was walking down a gravel road on Antelope Island and an
insect kept flying up in front
of me and landing a few feet
ahead and it kept doing this over and over. I'm sharp. It doesn
take me more than 10 minutes to figure out I should be trying
to photograph it. © Carol Davis 7-1-2014

small robber fly with prey
Robber Flies are sometimes easier to photograph when
they're eating and this one was
letting me get down to its level
 (which isn't easy for me with my bad knees) and take a
shots.  That little fly it's chewing on is very tiny, which goes
to show that even the tiniest
flies still have insects that prey
upon them.  © Carol Davis 7-1-2014

robber fly with large eyes
You know you have a cooperative Robber Fly when they let you
 get down and take a shot from
the front.  The eyes on this species
 are very unusual - they really pop out of their head (looks

a tad bit alien, doesn't it?)   ©  Carol Davis, 7-1-2014

robber fly on a pebble
So I could show you just how tiny this little robber fly was
(on a different day than the one above) I took the pebble it
 was standing on.
I put it beside a dime - you can see the
comparison below.  I think these two robbers might be
 the same or very similar species.

The tiniest of Robber Flies takes some luck to see
on a pebble this small.  The dime is about
9-10 mm wide. © Carol Davis 7-17-2014
