Robber Fly: Microstylum morosum

This is a Robber Fly and not an Assassin Bug and those gorgeous green eyes are pretty diagnostic that it is Microstylum morosum, a species also pictured on BugGuide.  According to Beetles in the Bush:  “Until recently, Microstylum morosum was considered a Texas-endemic.  However, Beckemeyer and Carlton (2000) documented this species to be much more broadly distributed in the southern Great Plains (from Texas up into Oklahoma and Kansas and west into New Mexico, Arizona, and Colorado), and Warriner (2004) recorded it shortly afterwards in Arkansas.”
