What kind of bug is this little lady? She is about an inch long and I believe she was laying eggs while I was snapping these photos. This was taken in my backyard on June 5th, 2015

Hi Connie,
This is a female Robber Fly, and we found a very similar looking individual on the Bandelier National Monument website, but alas, it is not identified to the species level.  Eric Eaton has an image of
Promachus albifacies from Colorado Springs that looks very similar, and researching that on BugGuide, we believe that at least the genus with members known as Giant Robber Flies is correct.  We are going to be out of the office later in June, so we are postdating your submission to go live during our absence.
