You may remember this photo of an unknown Hoverfly pupa - one of four - found during a search for Callicera aurata pupae with John O'Sullivan & Joan Childs a few weeks ago.
Well, John informs us that two of these beauties have now emerged. It's Criorhina floccosa, not a species you see every day. This photo - credited to Walwyn's Photostream on Flickr - shows a male. A male and female have emerged so far with 2 pupae yet to reveal their hidden secrets.
