And there is a mite (I Think) under the fourth tergite. Is it possible to say anything about possible mites on Coelopa? Unfortunatly I can´t make better Pictures of the mite at the moment.

Hi Krister, that "mite" looks similar to the Strepsiptera, I find quit often on wasps (stylopised wasp). I've never read about flies being parasitised by these "twisted-wing insects" but it seems to be possible. Eric |

Yes, I had some thoughts about Strepsiptera too, interesting! Maybe there are species who parasites on flies? |

These species exist: "Strepsiptera of various species have been documented to attack hosts in many orders, including members of the orders Zygentoma, Orthoptera, Blattodea, Mantodea, Heteroptera, Hymenoptera, and Diptera." (English Wikipedia, Strepsiptera). Can you try to make more fotos of the parasite? |

There are several legs on it, so it is not Strepsiptera - looks more like a mite! No better fotos so far unfortunatly. Krister |

The fine hairs on the legs suggest that this might be Coelopa pilipes

It definitly is Coelopa pilipes. There are frequently mites sitting on Coelopidae using the flies as transport from one heap of seaweed to another (phoresy). Those mites are usually not connected between tergites. I cant say what it is. Regards Xylo |

There is a 2009-paper about the mite Thinoseius fucicola on Coelopa seaweed flies, mainly the male ones: https://academic.oup.com/ee/article-abstract/38/6/1608/360395?redirectedFrom=fulltext&login=false- (unfortunately w/o any picture) Direct access to this paper, see reference list in the Wikipedia article about C. frigida: https://en.wikipedia.org/wiki/Coelopa_frigida Best regards, Volker |
