Some wasp(?) Photographed near Grand Canyon Caverns in Arizona, USA - Hemipepsis ustulata -
Located about 16km from the town of Peach Springs., Mohave County, Arizona, USA August 1, 2017 Size: Approximately 3cm
This was completely new to me. Desert environment after recent monsoon rains common at this time of year. Appears to be some kind of wasp, but without a stinger.
