A little heavier than a Musca domestica, but probably not much longer.

But silence of Experts tell us that in this case I'm not mistaken and it is realy Pollenia sp. So confirm your second photo. 2. Generaly you can ID Pollenia as Calliphorida without metallic shining body and with golden hairs (not seta) on thorax. Usualy Pollenia looks rather like: http://www.rosfoto.ru/shop/photo/31116/ But in spring I also met Pollenia species with very poor golden hair like yours. 3. Unfortenely genus level is last level for Pollenia ID by photo. Otherwise you have to examen males genitalia under microscop. Nikita Nikita Vikhrev - Zool Museum of Moscow University
