There were actually three Robber Flies in this drama at Promontory Point. The other one
finally gave up and
went over to sulk on the barbed wire fence.  © Carol Davis 8-20-2017

Sometimes you are the hanger and sometimes you are the "hangee". In this
case, the female is the larger so the male is the hangee.  © Carol Davis 8-

black robber fly
Here is the one that was left out - a male, I presume. It stayed here
 gazing off over the barren landscape
until I drove it crazy taking photos. 
This is only the second time I have seen these black Robbers.
They are gorgeous,
fascinating creatures with voracious appetit
es.  You can see more
of them here that we found near Eureka, Utah.  © Carol Davis 8-20-2017
