Photographed August 21, 2013. This is a rare Robber Fly. Until recently the last fly was collected in New Jersey in 1987. Shortly after I posted this fly from Wisconsin on Bugguide, several others were photographed in North Carolina. If you have photographed a fly similar to this, please post a photo or photos on Bugguide.net.bugguide.net/node/view/828011
