Following its discovery in 1997 there have been two papers and a number of expeditions by photographers to find the European Jester, Sphyracephala europaea
Nikola Rahme's blog at http://buprestidae.blogspot.co.uk/2010/ … lfold.html is an account (in Hungarian) of a 2009 photographic expedition
Nikola is a prize-winning photographer with a Flickr site and there are many more photographs of Sphyracephala europaea there. For example at https://www.flickr.com/photos/eurythyrea/5126015816 and a stacked frontal view of the head at https://www.flickr.com/photos/eurythyrea/5135595446
Other Hungarian dipterists have gone looking for it, Yordan Kutsarov at http://insecta.pro/taxonomy/334303 and Walter Pfliegler on Diptera.info and at http://naturephoto-walter.blogspot.co.u … ngarn.html
It's on the Danube and there's mention of records in Bulgaria but I'm unable to trace any records from that country.
