Black Bee Killer with a Wasp (Robber Fly)

I'm certainly glad these guys don't weigh 3 pounds! Amazing creatures...they wait patiently along the Guadalupe River bottom watching bees and wasps work flowers and mud, regular bee/wasp activities, before flying out from their hide and seizing their prey in mid-air. After the seizure, they perch and dine. Drama is everywhere and who needs TV?!?!?! :)
