Hello, several of these tiny (2 mm) Psychodids I find at the bathroom sink since a week or two(northwest Germany).

I don't know. It has the wings folded, so it should be a Psychoda spec. But they are anything between white and grey, not blackish. Try to make more pictures. And when you find a dead one, look at the last segments of the antennae under a miscroscope. |

Hello weia, thank you for your reply. weia wrote: they are anything between white and grey, not blackish. I know the "normal" Psychodas, but this is not a single case. There are several of them, all completely black. I have also seen a mating couple. Try to make more pictures. I will try, but I doubt, that I will get much better photos. They are so small... And when you find a dead one, look at the last segments of the antennae under a miscroscope. I can only try a magnifying glass, I don't own a microscope.

You come quite far with the antenna. I have only knowledge of the species of the Netherlands and Belgium, so with some reserve: it looks like subspecies Psychoda, which in my region contains 3 species. It looks much like Psychoda (Psychoda) crassipennis, but I have never seen one in a collection, so I don't know its colour. Crassipennis means 'thick wing' |

Did you watch the mating behaviour? Before and how they find each other, duration? |

Thanks again for your reply. weia wrote: Did you watch the mating behaviour? Before and how they find each other, duration? I only saw one couple already together, abdomen to abdomen. They sat there at the wall quite a while. Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |
