Laboulbeniales on Diptera
by Jan Máca

Enclosed photographs show Scaptomyza graminum infested by Stigmatomyces sp. on abdominal tergites, and enlarged Stigmatomyces from ther same host. The parasite is ascomycete fungus of the order Laboulbeniales, familiarly named "laboulb". Six species of laboulbs (genera Arthrorhynchus and Stigmatomyces) from Diptera were published from Czech Republic by Rossi and Máca (2006) (DOWNLOAD), three more species (from Scaptomyza graminum [Drosophilidae] - see pictures, from Spelobia [Sphaeroceridae] and from Parydra[Ephydridae]) were found there recently. From most European countries there is no information about laboulbs, so that their geographic distribution there is not very clear. Tropical countries are rich on laboulbs but it is presumed that most species are still undiscovered. Only the "higher" diptera (Cyclorrhapha) are infested.

The biology of laboulbs is very interesting - see e. g. Majewski (1994) or Santamaria (1998), both quoted in the above mentioned paper. Preserved (dried or alcoholized) specimens of flies with laboulbs would be greatly acknowledged by W. Rossi (email) and/or Jan Máca (email).


The photograps, made by Dr. F. Weyda, are SEM ones, thus not "true-color" ones. The laboulbs are usually brown.

I'll try to collect all flies with fungi from now!

I found a Pelina (Ephydridae) with many 'laboulbs' a few days ago. Collected and pinned Smile

During the last few weeks I collected many drosophilids by means of a wine trap (canopy trap). Several of these drosophilids have laboulbs. I will contact Jan M?ca.

Yesterday I collected Discomyza maculipennis (http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=10224) with nice Laboulbeniales Grin

It took me long enough Smile but I finally sent a number of drosophilids (Drosophila subobscura) to Dr. Rossi (Stygmatomyces majewskii ??).

Occasionally I find growths on water beetles that appear to be fungi, such as

Are you able to say whether these are Laboulbeniales, please?
