Hello! This 4 mm fly rotated its wings like a Sepsis, but I think it must be a Geomyza (Opomyzidae). But which? Found three days ago on a meadow in Ostwestfalen/Germany. Thanks in advance!

Looks like Geomyza balachowskyi (female) to me. Jan Willem |

For comparison, here's a male of G. apicalis (det. Kahis, so treat with caution  )

Hello, all! Many thanks! Mostly I found Geomyza tripunctata here, but this one looked differently. Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

Jere - Are those Laboulbeniales on your apicalis abdomen? Your fellow countryman, Larry Huld?n, would be interested to examine this specimen if he hasn't seen it already! Tony ---------- Tony Irwin |

Well, this is the first time I have heard about Laboulbeniales, but after a some googling for images: yes they are. I have seen them on flies every now and then, but unfortunately I haven't kept record of which flies have them. The specimen was collected with a Malaise trap (in alcohol), hardened in acetone (no all DNA is lost) and dried. By chance I photographed this fly also before drying. Here's the abdomen with attached Laboulbeniales: Kahis attached the following image:  [16.43Kb] Kahis |

From what I can see this is Stigmatomyces, perhaps Stigmatomyces geomyzae (Ascomycota, Laboulbeniales). But we would need to see the specimens closer (under microscope) to be sure of identification. Just keep tracking them! Best, Danny Edited by Danny Haelewaters on 20-08-2012 16:21 Danny Haelewaters https://dannyhaelewaters.com https://twitter.com/dhaelewa |
