Anthophora abrupta, M, Side,PG county, MD
Male, this fun species nests in the walls of my adobe walled house where it aggregates in large numbers where the adobe is thickest. They create small dropping tunnels at that project out from wall ...function unknown. Note the massive tongue, unclear, to me at least, as to why, but likely has to do with what flowers it is accessing. Original public domain image from Flickr
