I assume this is Calliphora vicina. But, I read somewhere (can't remember where, maybe here) that there's a similar species but different in autumn. Which species can be confused with C. vicina and could this be one? cyprinoid attached the following image:  [153.58Kb] Edited by cyprinoid on 21-11-2009 20:17 Hyperbolizer |

Which species can be confused with C. vicina and could this be one? Here is the one you were thinking of Hakon. The best place to find recent threads is (in your case); Go to Forum Search...type in Calliphora...Sort; Click on Descending....Here's one I prepared earlier..http://diptera.in...d_id=25713 Roger Looks like C.vicina but....

This is vicina, only Calliphora with red gena. Theo |

Thaks Theo. There seems to have been a mass awakening these days. I have found a few fresh specimens in my garden. Hyperbolizer |

Look for dark individuals, might prove to be something of interest (like loewi) Theo |

Thank you Theo, I will look out for Calliphora without red gena. Hyperbolizer |

Note that C. uralensis and subalpina have also quite yellow-orange gena! C. loewi is fairly common up here in North. You just need to go "into the wild", bit further from human dwellings. They visit flowers (Umbelliferae), so easy to pick. Since you live in Norway, beware of the more arctic species S. stelviana and genarum. |

Thank you Jaakko for interesting information. I will take longer excursions next summer.

Really Jaakko, I'd never seen that ! Anyway, the anterior spiracle is yellow as well in the pic, so it really is vicina. Species other than vicina and vomitoria are man-avoiding in my experience. Genarum should be rather common in northern Scandinavia. It is much smaller and might even be overlooked as Calliphora. Theo |

Here's couple of images of C. uralensis, both quite soaked. Irritatingly vicina-like: dark calypters etc, however the anterior spiracle is a striking difference and basicosta is black! Until recently, I found calliphorids bit unmotivating and haven't collected any serious series. Jari F should have examples of subalpina, so he might post a potrait here as well. C. subalpina is easy to spot apart from these two from the clean-white calypters.

Here are some pics which were thought to be C.uralensis from last year in this thread http://diptera.in...d_id=15828 Not seen any other postings of C.uralensis that I can think of... Roger Thomason attached the following image:  [156.69Kb] Edited by Roger Thomason on 01-12-2009 06:33 |

Hi, As the calypters seem infuscated, uralensis is the only option to me. |

To make things simple: C. vicina = yellow/red gena + yellow/red anterior spiracle. Anything else is (more) interesting? Depends on what is ment by pale in the description of uralensis.  For the record I found one tonight on my porch light, I have not had time to study it yet. Probably C. vicina. Hyperbolizer |

Yes, the main point of vicina is that the epaulette is yellow, whereas in hothers it is black. However, this feature can be very very tricky in pictures due to shadows of flashlight. In collected specimens, it is no problem in my experience. Theo |
