Mexican Cactus Fly

July 31, 2015

The GNG had a very interesting visitor today, a Mexican Cactus Fly.  This is the largest flower fly in Southern California (with a body length of ¾”) and ranges from the Southern U.S. down to Central America. The fly itself resembles one of our larger carpenter bee species, but on closer inspection it is clearly an enormous fly!
