yes  This fly is distinctly spreading North currently, last September I collected a specimen in Moscow region. Now Poland, not as cool as Russia, but without doubts not Africa too! Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Nikita – in Northern Europe it's always going to be C. albiceps, yes? I hadn't realised it had spread so far

Hi Susan! 1. Ch.megacephala recorded in Spain, but even in North Africa it is uncommon. It becomes common in Oriental. And Ch.megacephala males have enlarged facets in upper part of eyes. 2. Ch.albiceps is common even in Russia on Black Sea shore. On the other hand even in Turkey, if you collect outside sae beach, for example, in forest, Chrysomya is replaced by Lucilia. So, if Marek found Chrysomia in Poland, I bet it was Baltic Sea beach Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Hello, not at all! The yesterdey Chrysomya (albiceps, I guess) was observed and photographed on thistle flowers in our uniiversity in Warsaw (Ursynow). It was not shy, but closer approach was ruined by a bee that landed on the same flower and frightened away the fly for good. I will visit this place today but the waether is rather not for flowers visitors, cheers! Edited by mwkozlowski on 13-10-2008 10:28 very general entomologist |

So I should assume it may already have reached me in central France (where I spend half my time these days), even if it hasn't made it to Essex yet? I always thought of Chrysomya as much more warmth loving than many of the Lucilia. Warsaw and Moscow don't quite fit my idea of warm places (if you will pardon the comment, Nikita and Marek  )

Think again. The summers are hot there, apparently that suffice for Chrysomyia. Theo |

...bu are we convinced that on the picture is M. albiceps? I just have learned that my observation can be the second score of Chrysomyia in Poland. First time it was found one year ago also in central PL. very general entomologist |

It is Chrysomyia, technically we cannot see that it is albiceps, though we can see it is NOT megacephala. And there is really no other possibility. So yes, we can be sure, I think Gratuluje, Theo |
