Hi, I got hundreds and hundreds (if not thousands) of these from my beer traps. I was thinking Drosophilidae but now when I'm drying and pinning them, I noticed the bare and long arista. They collapse very badly after drying so these two flies are not complitely dry yet. The only possibility with the Drosophilidae key would be Cacocenus (scutum, scutellum and orbital plates without stripes, arista microtrichose, ocellar setae present, wings hyaline, ac at least 12 rows) but these become brownish as the dry. Is there enough details visible to tell something ? July 6.-7. 2010 Loviisa, Finland and from beer trap. Jari JariF attached the following image:  [141.57Kb] Edited by JariF on 09-02-2011 20:12 |

Why not - at least there are not any other so far recorded Finnish alternatives with such an arista. I could vote for your theory, if you have read the LENGTHY description of the species in the FES volume and everything is OK. I haven't ever caught that species but seen it a couple of times. An interesting species it is. But this weekend I also recorded a new drosophilid (genus) for me, namely the tiny Microdrosophila zetterstedti. Just by sweeping, haven't got any traps in use. |

Thank's Kaj. I will try to run the key with next ones before they get dry. These small flies seems to love our "Kukko" beer  Jari |

That's one species I didn't collect in my beer traps. Maybe I should have used "Kukko" beer too  .Do you also get a lot of specimens of Drosophila subobscura in your beer trap? And if so, have you already found specimens with Laboulbeniales? I found rather many of those. Edited by Jan Willem on 16-08-2010 07:28 Jan Willem van Zuijlen |

Are you sure its a drosophilid? My first thought was Milichiidae,

The beer traps works so fine, that I really have far too many specimens to work with. Hundreds of Muscidae, Heleomyzidae, Calliphoridae etc. but only two Odoniidae found so far Jari |

Hello Jari, Yes, I know the problem of the large number of specimens  . In a year time I collected 33120 specimens with a single beer trap (29396 Diptera; 23096 Brachycera and 6300 Nematocera).@Mark-uk: Not a very good picture, but you get an idea of the trap I used.

That's very useful - many thanks Which Kukko do Diptera prefer, Pils, Lager, Vaalea or the Portteri? I can't help but think an English Ale would work better? |

I know Irina Brake is away on field work for probably another month, I expect she can give you a more definitive answer when she is back? Mark |

I think I have one Lispe with that...  http://www.dipter...g_5568.jpg - take a look at the margin of the eye...

Kahis has now seen these flies and they are indeed Milichiidae. |

It is very possible to find Laboulbeniales on the eyes. They can be found anywhere on the host's body. As an example: see the picture in attachment: Laboulbenia giardii on the eye of Dicheirotrichus gustavii (DH37, ADK5163), found in The Netherlands (Friesland) [picture made by André De Kesel, Meise Botanic Garden, Belgium]. Do not hesitate to contact me (danny.haelewaters[at]gmail.com) if you would have further questions. jorgemotalmeida wrote:
