Am I right that this is Calliphoridae? The overall color was a sort of metallic blackish green. Garden near house, not far from woods, West Virginia USA, 3 September 2006. Is it possible to ID further? Thanks in advance for any help! Stephen attached the following image:  [119.71Kb] --Stephen Stephen Cresswell www.americaninsects.net |

I think it is Muscidae, Stephen. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Yes and Muscinae. Maybe Morellia - bluish-black (maybe green to you or in U.S.A.), white-dusted stripes on thorax. |

Thank-you Nikita and Robert. It seems I am often fooled by Muscidae!

One of my other posts from today has the question, is it safe to say with Muscidae that with the eyes far apart like this it is a female? I am never sure which families have this "rule" and how reliable the rule is. So I am thinking this is a female assuming the rule is reliable for Muscidae? --Stephen Stephen Cresswell www.americaninsects.net |

As with all rules, there are exceptions. Usually in Muscidae the females have eyes far apart like this, and the male eyes are very close together, but there are also some males which have eyes far apart. In the Tachinidae, there are a few females which have eyes almost touching, and are easily mistaken for males.
