Unknown bee found inside Opuntia blossom, Dry Island Buffalo Jump Provincial Park, Alberta.
Any help with bee I.D. would be appreciated.
Note 23/07/2010: I submitted this image to BugGuide, and it has been suggested that this may be a male Diadasia (Coquillettapis) australis (Cresson), which may not have been recorded before in Canada.
