Hello, I've found that fly at 24.07.2007 in Finnland (Aland-Islands). Without functionable wings it is major difficulty... Size like Musca domestica (perhaps it is Musca domestica?) (ca. 8 mm). Who can help? Axel Steiner attached the following image:  [38.82Kb] Edited by Axel Steiner on 05-03-2008 16:13 Best regards!

This fly has only just emerged from the puparium, and has not yet pumped up it's wings |

This fly is emerging. Had you waited another hour, you would have seen the fly pumping haemolymph into its wings thereby expanding it, and than the fly would have flown off. I can not comment on the species. Edited by Xespok on 05-03-2008 19:31 Gabor Keresztes Japan Wildlife Gallery Carpathian Basin Wildlife Gallery |

It is not Musca but some other muscoid fly (Muscidae or Anthomyiidae, it is difficult to tell with such a 'newborn' specimen)

Looks like Pollenia to me (Calliphoridae). I remember these youngborn crawling about frequently in offices and such... |

The feet are big. Sarcophagidae? |

I doubt it is Pollenia - no pale curly hairs are seen. I suspect crex is right (and thus I am wrong  )

Thanks for explanatory notes and the determination to all of you. I think Sarcophagidae is a good idea :-) Best regards! Axel Steiner --------------------------------- Breckerfeld, Germany www.natur-in-nrw.de |

The red eyes and prominent bristles suggest a sarcophagid. I have heard that some flies can remain teneral for quite a long time - up to 48 hours I think. Can't remember the source for that though. |
