I've seen a lot of those little Scathophagidae (about 3mm), flying around Corydalis solida. Sometimes they were resting on flowers (pic 1 - 4) or leaves, or seemed to oviposit on husk (pic 5). (Belgium,27-3-2012) What could it be ? 1 a Christine Devillers attached the following image:  [118.56Kb] Edited by Christine Devillers on 29-04-2013 11:44 |

Could you tell me if there are species known as miners of Corydalis or other Fumariaceae ? Here is another picture showing a female ovipositing in the pod (fruit) of Corydalis solida. Christine Devillers attached the following image:  [158.12Kb] Edited by Christine Devillers on 24-03-2013 11:38 |

Acerocnema macrocera (Meigen, 1826) maybe? See Stuke, J.-H. & Schacht, W. (2009): Die Dungfliegen Niedersachsens und Bremens (Diptera, Scathophagidae). - Entomofauna 30: 221-256 |

Hi Christine, This is a truly spectacular fly! Very nice! The publicatoin is available here: http://www.landesmuseum.at/pdf_frei_remote/ENT_0030_0221-0256.pdf No info on host plants, but an indication for early presence is there. A reference to an identification key is there, but I lack that publication. Did you spotted this again in your garden? Bye Jonas |

Thanks for the link Jonas, the mention of Corydalis "Die beiden Belege von Bad Bentheim wurden an Lerchensporn (Corydalis spec.) gefangen und später gezüchtet" is very interesting. Unfortunately, I've only seen them the 26 and 27 March 2012. Edited by Christine Devillers on 29-04-2013 11:24 |

I just received confirmation from a specialist of Scathophagidae. He is sure that it is Acerocnema macrocera. I find no data of this species for Belgium in databases on the web. Maybe a new species for Belgium? |

This year, I saw them again in my garden (males, females, matings) in April. Here are two pictures of a male (3mm, 14-04-2013,Spa,Belgium). I've also seen females of Ichneumonidae (Diplazontinae?) ovipositing in the fruits of Corydalis solida. I guess they tried to parasitize the eggs or larvae of Acerocnema macrocera. Do you have informations on the parasitizing of Acerocnema macrocera ? Christine Devillers attached the following image:  [148.55Kb] Edited by Christine Devillers on 29-04-2013 11:39 |
