Metallic Green Bee on Aster Flower. (Metallic green bees and cuckoo wasps look incredibly similar, but this blog post leads me to believe that this, like most if not all similar bugs I see on flowers, is a bee.) Photo taken near Wollaston Lake, Ontario. Photograph copyright Matthew King. Available as an 8×10 print, matted and framed. E-mail firstname.lastname@example.org to inquire.
