this bee was seen today in gypsy steppes of Saragossa, NE Spain. It looks like an Sphecodes with black head and thorax and bright scarlet abdomen, but it's legs are red and all Sphecodes that I've seen have black legs, also it have a completely red abdomen without dark tip, dark wings, and it's quite big for an Sphecodes, almost the size of a honeybee. So I'm completely lost with this one.
Unfortunately this is the only photo that I've got. When I tried a lateral one, the bee flied away.
Please help!!!!!!! Thanks!
