This cute little honeybee sized guy is among the many species of Robber Flies, but this Bee Fly Diptera: Bombyliidae is another family of flies. When he is not on cameras, he can be found checking out the pollen of the flowers, and on the ground. This species lays its eggs in soil and takes a year to complete the life cycle. The larvae are parasitic on immature stages of other insects and therefore is considered beneficial.
Reviewing pictures we have taken, I found a shot of the bee fly building his burrow in the ground. I did not realize until recently, what the identity of the insect was.
