Wasp-like insect on Black-eyed Susan - Epeolus lectoides -
North Judson, Starke County, Indiana, USA July 16, 2016 Size: medium-small
Photographed in a mostly native sand prairie garden, it reminds me of a Bicyrtes wasp, but maybe not quite. Something in Bembicini perhaps? The flower is Rudbeckia, most likely Rudbeckia hirta.
