Since it appears now that only Wikipedia - the free encyclopedia lists the phantom name (Michigan having removed it form their database) I have edited the relevant page in Wikipedia (by the people for the people) and removed the phantom name form the list of Pollenia species. Check it out. http://en.wikipedia.org/wiki/Cluster_fly You can also compare various versions of this page and see the name of the person who deleted it. The name is retained in older versions of the page (see the "history"). Anyone wanting to reinstate it? Knut Rognes
