Only seen this once before on a fly but it is more frequently seen on ladybirds (those yellow pointy patches). see http://books.google.co.uk/books?id=_n1vr0_RbXoC&pg=PA835&lpg=PA835&dq=Laboulbeniales+on+bees&source=bl&ots=KvHr4RLCVe&sig=PeYrTvkOeWgyWI7SYBy9NyYLqtk&hl=en&ei=J7MxTvj7H42yhAexmLCLCw&sa=X&oi=book_result&ct=result&resnum=1&ved=0CBcQ6AEwAA#v=onepage&q=Laboulbeniales%20on%20bees&f=false for more info Brian V.

Brian, I'll send your e-mail to Dr. Walter Rossi - Laboulbeniales expert, he wants to contact you. Nikita Nikita Vikhrev - Zool Museum of Moscow University

I also sent a number of specimens of the obscura group to him for identification of the Laboulbeniales. It looks like the same species to me (but that doesn't count for much ). If that is the case, it would be Stigmatomyces majewskii. Jan Willem

Another Laboulbeniales specialist (De Kesel) told me that it's important to know the host, at least for beetles. Mushroom season is almost over, let's start to check drosophila specimens.

Ten orders of Hexapoda are known to host Laboulbeniales: - Blattodea (cockroaches) - Coleoptera (beetles) - Dermaptera (earwigs) - Diptera (flies) - Hemiptera (true bugs) - Hymenoptera (ants) - Isoptera (termites) - Mallophaga - Orthoptera - Thysanoptera. Some 80% of the more or less 2.000 described species of Laboulbeniales parasitize Coleoptera. There seems to be more laboulbenialean diversication in Staphylinidae (49 genera, with relatively few species per genus) than in any other family. In Carabidae we have only recorded 15 genera so far, but these sometimes have hundreds of species in one single genus (Laboulbenia).
